Join us in the CHAT SHOUTBOX tonight during tonight's episode of Big Brother starting @ 8PM ET.

Tonight, we are halfway through Big Brother 27. Time for Reality Royalty to do what she does best - shake up the House and make her mark on the game. Welcome to Live Eviction Night on Big Brother!

Previously on Big Brother, Vinnie double-dipped into a lot of final twos, with Lauren, Kelley, Rylie, and Morgan. Plus, he and the gamer were in the Melting Pot alliance with Mickey. With the Red Queen in charge, it wasn't floaters who needed life vests as she gunned for some major players. With the former winner looking to fortify her game, she made an unholy alliance with Keanu.

At the legendary OTEV competition, the lady from Lafayette latched onto power. She wanted to save her top ally, Vince, but was worried about upsetting Rachel. At the Veto meeting, Lauren threw her friend a life vest, leaving Mrs. Rylie to put up Rylie.

Tonight, will the showmance be torn apart? It all comes down to who wins safety in the BB Blockbuster. And then, the next Houseguest will be evicted. All this, right now, live on Big Brother!

Good evening, I'm Julie Chen Moonves. Welcome to Big Brother.

It's Day 45 in the Big Brother House, and Rachel's reign as HoH has been filled with the drama that is the hallmark of her Big Brother legacy. But with the block loaded with big players with big personalities, one must be evicted. So is Rachel prepared to deal with the retribution of those who make it through the night? We'll all find out soon enough.

But first, a shocking Veto meeting has left some in tears for their allies, some angry at their allies, and some trying to remember who their allies actually are.

Day 42. Keanu thought being in a Final two meant Rachel would consult with him on these kinds of decisions. He would not have OK'd this because she just attacked his side of the House. Rachel says it was dumb for Lauren to use the Veto, but putting Rylie on the block was the best power move. He's a competitor and has a whole house that loves him. Hopefully, these newbies will take the shot.

Rylie puts his life on the line, literally 8 seconds at a time, so he's not scared of being on the block. This is what he does. Morgan is happy the Veto was used on Vince, but she's sick to have to campaign against Mickey. She wants to win BB Blockbuster so she can vote to keep Mickey.

In the Storeroom, Kelley comforts Lauren, who is scared of Rachel's retaliation. She firmly believes she made the right decision to save Vince. Katherine and Keanu come into the Storeroom, and Lauren immediately apologizes to a sobbing Katherine. Why did you use it? Rylie's safe, Kelley assures her. No matter what, Keanu adds. We've got four right here, and Vince, Kelley tells Katherine. She and Lauren hug it out through their tears. Why did she do that, wonders Keanu out loud, placing the blame squarely on Rachel's shoulders.

In HoH, Ashley and Will are quick to tell Rachel she did well. It was the only move I could make, Rachel says. She doesn't want them to think she was making decisions without them (even though she did). I cosign that move, Ashley gushes. Mickey joins them to ask if Rachel is OK. She wasn't expecting that, she says. Mickey is confident she has the votes to stay with Ashley, Will, Ava, Katherine, and maybe Lauren if she votes with the group like she always does. The worst case is Morgan and her against each other. They are all confident that it will be a blowout to send Rylie home against either Mickey or Morgan.

In the Have-Not room, Kelley asks Vince if he's that close with Lauren. Vince plays it off, saying that people keep claiming he's close to everyone. Last week, it was him and Morgan. We're not THAT close. Even Keanu doesn't know we're final two, Kelley says. Right, says Vince. I don't remember making a Final two with Kelley, Keanu says privately (it was Day 02). But obviously, sure, why not? Of course we're still final two, Vince assures her.

In the bathroom area, Vince tells Rylie he has never, and will never, question him, and will always keep him no matter what. Rylie thanks him. Vince says he's been working with Rylie since Day 1, though they don't technically have an alliance... Well, maybe he does have a Final two (also on Day 02). If it came down to you and Morgan, Vince assures Rylie, I know you will protect me. But if Mickey wins Blockbuster, Vince confesses to us that it would be terrible. In the Have-Not room, Morgan asks if Vince will vote Rylie out. I'm keeping you and Mickey, Vince promises. Mickey joins them, so Vince repeats his promise to keep her over Rylie. This is the best chance for all three of us to stay, she tells them.

In the Orient Express bedroom, Mickey and Katherine count the votes using M&Ms. Mickey tells us she needs Katherine and Rylie's vote to keep her over Morgan. But Katherine tells us that she's leaning towards evicting Mickey if she's still on the block after the Blockbuster. Morgan walks in and sees Mickey and Katherine brushing away the M&Ms, and she knows that means they were counting votes. She never wanted to campaign against Mickey, but she can't trust her.

At the dining table with Katherine and Rylie, Mickey remarks to Ashley that she's been in Rachel's HoH room more than when she was HoH. Ashley is ticked off, thinking Mickey was planting the seed with Katherine that she's the reason Rylie was on the block. Never one to let sleeping dogs lie, Ashley lets Rachel and Will know what Mickey said (proving Mickey right). She is blaming you for Rylie's nom, Rachel points out. Morgan would never say something like that, Will argues. He tells us Mickey is not a team player.

Later, Morgan stokes the flames, telling Ashley that Mickey thinks Ashley would benefit the most if they were out of the game (Day 42). She's become Rachel's #1, Morgan recalls Mickey saying. In the DR, Ashley questions how they are supposed to be allies. Maybe Mickey doesn't want my vote. Will and Rachel join Mickey and Morgan in HoH, and Mickey's aggressive game is the topic. She was the first person who said Rachel's got to go, Morgan notes. They always felt like just a number to her. Morgan is hopeful that other Houseguests are getting sick of Mickey, so maybe she wouldn't go home against her.

Ashley and Will announce that Morgan has their vote. That doesn't sit well with Rachel, who urges them all to be more open with each other. They decide to form a "real" alliance, but Morgan wants to include Vince. Rachel says she'd like working with him, but has been under the impression that he wanted her on the block. Vince enters tentatively as Rachel offers to include him in an alliance. Morgan suggests they be called The Judges because they decide who goes home. They all love the idea.

Morgan hopes this alliance solidifies the votes for her. Rachel laughs that she's in an alliance with two of her nominees and also with Keanu, whom she wanted to murder a week ago. BB12 Rachel would have drawn 5 lines in the sand by now, but BB27 just makes alliances. Ashley tells us that if it is Ryle vs. Mickey, they'll give Mickey another chance. But if it is Mickey vs. Morgan, bye-bye Mickey.

It is time for the BB Blockbuster. Rachel targeted Mickey to avenge Jimmy's eviction. Rachel targeted Rylie to teach Lauren a lesson. And Rachel targeted Morgan for implying she would only make it to the Jury. Who will win their safety and live to fight another day?

This competition is called Settle The Score. The three nominees will have two minutes to roll their ball down a snake-shaped ramp, dropping it into an increasingly higher numbered score zone, from 0 to 40. After taking their shot, they can lock in their score or throw that score away and try again. The player who locks in the highest score after two minutes wins immediate safety.

Mickey is on the blue table, Rylie is on the yellow table, and Morgan is on the purple table. Mickey throws her first ball down the snake. Rylie has a more nuanced approach, but all three choose to start over. On his second roll, Rylie slides down to a 29. He watches to see whether Morgan or Mickey can match it, but has not locked in his score.

With 1:20 left on the clock, Morgan matches his 29 with one of her own. She quickly locks in her score. At some point off-camera, Mickey landed a 38. Rather than take advantage of the more than a minute remaining on the clock, Rylie gives up and locks in his 29. That means Mickey has won the BB Blockbuster!

A stone-faced Mickey waits for Julie Chen Moonves to make it official.

Katherine offers Mickey polite applause when they return to the Living Room, but you can see nervousness in her frozen smile. Vince moves to ask Ava what she wants to do. Rachel interrupts, telling them they have to keep Morgan. Rylie starts his eviction speech early, announcing he won't campaign against Morgan. Lauren whispers something to Vince and Keanu. Rylie and Morgan take their seats, and Kathrine takes Rylie's hand. Keanu and Vince confer in the kitchen. Rylie was going to put up you, Kelley, and Rachel, Vince tells him. Keanu doesn't believe that. Do not do this, he tells Vince.

It is time for the live vote and eviction. Rylie says it's been an honor, keep him if it is best for their game. Morgan is one of the kindest-hearted women he's ever met, as strong as they come. Morgan says if it is up to either of us to stay, we'll stay. She came to play the game with honesty and loyalty, and will continue to fight. This is a dream, she says, fighting the tears.

It will take 5 votes to evict, and there is no tie-breaking vote.

Mickey votes to evict Rylie.

Katherine votes to evict Morgan.

I'm so sorry, man. Vince votes to evict Rylie.

Ashley gleefully votes to evict Rylie.

Will votes to evict Rylie.

Ava signs and asks if she can still vote Mickey. No, Julie Chen Moonves says. Ava votes to evict... The name won't come off her tongue. I vote to evict Rylie.

Kelley votes to evict Morgan.

Lauren votes to evict Morgan.

Keanu votes to evict Morgan.

All of the votes are in. Julie Chen Moonves gives the results to the Houseguests. By a vote of 5 to 4, Morgan, you are safe. Rylie is evicted from the Big Brother House.

Mickey is the first to hug Rylie as Katherine breaks down in tears. He takes her into his arms, as she sobs uncontrollably, their heartbeats pounding into their microphones, beating as one. Will consoles Ava, while Mickey and Morgan embrace. Keanu is stone-faced. The other HGs just mill about, not wanting to interrupt Rylie and Katherine. Kelley takes over, offering Ava comfort. Mickey is crying in Rachel's arms. Rylie and Katherine continue to hold each other close. Stay strong and you'll be OK, he finally whispers, letting her go.

Rylie and Keanu engage in a tight embrace, Keanu fighting to keep his emotions in check, while Morgan and Vince hug. Ashley tries to offer comfort to Katherine, who doesn't seem to be aware she's there. Julie Chen Moonves reminds Rylie she's waiting for him outside, but Rylie gives Vince a hug instead as Keanu brushes away his tears. I love you, Vince and Ava both tell Rylie. Will gives Rylie a quick hug, followed by a crying Lauren and Morgan. Thank you for everything you did for me, Morgan tells him.

Ashley is the last one to say goodbye before Katherine, waiting by the door, falls into his arms once again, sobbing. It's OK, he tells her, kissing her on the forehead. Bye y'all, he says, grabbing his bag and heading for the hotel exit. He stops to give Katherine one last kiss on the lips, causing her to lose her composure all over again. Bye, she cries as he walks out.

What a journey, Rylie tells Julie Chen Moonves. Let's ask away, he says. He thought he had the votes to stay and didn't know what happened. He pauses for a second, then says Rachel was doing a lot of manipulating, but he won't badmouth anybody. He thinks Vince voted for him, and Julie corrects the record. It is what it is, Rylie says resignedly. You can't change nothing 'bout it now. Julie reads that Mickey, Vince, Ashley, Will, and Ava voted him out. That's crazy he says. He blames himself for his eviction. He had the opportunity to win Blockbuster but locked in with 29, the same as Morgan. There is nobody to blame but myself. Nobody else is responsible for my eviction.

Rylie says from the moment he saw her, he was drawn to Katherine's smile, the way she cares. Her heart is real. She makes him feel like the only man in the world. He fell hard and fast for her, and he did tell her he was going to marry her one day. He laughs, surprised we heard that. Oh, we heard it, Julie jokes. He didn't plan on it, but love knows no boundaries. He's not mad; she's an amazing woman, and he'll appreciate that no matter what happens.

Asked what is harder, riding a bull or playing Big Brother, Rylie says he's been riding bulls for 15 years, so it's easy for him. Big Brother is harder. He appreciates all the love and support, and it's been an honor to live the dream.

Taylor and Derrick are back to preview the next episode of Big Brother Unlocked, which will air on Sunday at 9PM after the 8PM HoH and nominations episode. Taylor announces that the iconic Wall competition will be tonight's HoH competition which Taylor won after 47 minutes. They will also pay a visit to Will's family and a special announcement from a BB Legend.

Now it is time to reveal the Mystery Guest for the Unlocked episode. The clues are amber stones, a cup of tea, and the Survivor logo. That could only mean that the Mystery Guest is Boston Rob. One of the greatest reality show players in history, Julie crows, playing Survivor 5 times, winning once, meeting his future wife, with whom he came in second on The Amazing Race. Rob points out he doesn't drink tea, though. Derrick points out it's Boston tea. You want something stronger, Julie asks? Coffee, he jokes.

Can you handle three months in the BB House? Boston says you have a shelter over your head and can eat. But with these lunatics, I don't know. Sounds like a challenge, Julie says. If he comes back, maybe I'll come back, Derrick challenges. Not me, Taylor says.

For now, let's listen in on the Houseguests. From outside the Big Brother House with Derrick, Taylor, and Boston Rob, I'm Julie Chen Moonves. Love one another.

Inside the house, Ava is still heaving tears as Morgan tells her to take deep breaths. Ava is sorry (for voting against Morgan). It's OK, Morgan tells her. Katherine is standing alone, drained, perhaps thinking of Rylie or contemplating her revenge.
