Today is the day that Barry has feared since before 2017 began, the day that Savitar is supposed to kill the love of his life, Iris West.
Barry: Okay, is everyone clear on what they are supposed to do?
Everyone nods.
Barry: Okay, great.
Barry and Iris leave.
Barry: Are you okay?
Iris: I'm fine.
Barry: Iris, you don't have to pretend you're calm for me, it's okay to be a little scared.
Iris: Barry, I'm not worried, I know that you are going to save me.
Everyone else is on the Waverider.
Snart: Calm down Raymond, this isn't helping anyone.
Ray: Sorry, but we've never really faced something like this before, an almost invincible enemy that knows everything there is to know about each and every one of us.
Sara: We've fought alien invaders, an immortal psychopath, and the Legion of Doom, and we've always come out on top, we have a plan, we'll be fine.
Ray: When has anything ever gone according to plan, for anybody standing in this room?
Stein: Excellent point.
Nate: Yes! Sara finally used the name I gave to Darhk, Merlyn, and Thawne.
Sara: Only because I didn't want to waste time listing all their names.
Nate: I'll take it!
Snart: You seem pretty happy for someone who just found out that they're gonna die soon.
Nate: How do you know I'm the one to die?
Snart: There's a reason why Mick calls you "Haircut 2.0."
Ray: Mick, do you really think he's an improvement over me?
Mick: He talks less and his armor is built in, but that's it.
Ray: Well, how am I better than him?
Mick: You put more thought into your haircut.
That got a little chuckle out of everyone.
Nate: At least I have hair!
Mick: Okay.
Ray: Wait, Gideon!
Gideon: Yes, Dr. Palmer?
Ray: Show us the last picture of Mick before he lost his hair.
Snart: Oh, you guys are gonna love it.
Mick: Haircut, you son of a bitch!
Gideon pulled up a mugshot of Mick.
Gideon: This is Mick Rory, 1993.
Everyone but Mick was laughing, so much that they couldn't even breath.
Sara: Oh my God, is that a mullet?!
Mick: Shut up! It was the 90's!
Ray: Oh man, I wasn't expecting that!
Mick: Damn it, Haircut, once I get my hands on you, I'll shave your head!
Ray: Oh shit, time to do my best impression of Speedy Gonzales!
Ray runs out of the room.
Mick: Haircut!!
Mick runs after him, and Rip enters the room while drinking rum, once he saw the picture, he did a spit-take.
Rip: What the hell, is that Mr. Rory?!
Nobody could stop laughing long enough to answer him, so they just nodded.
Rip: Oh my God!
Then Rip started laughing right along with them.
Team Flash is at STAR Labs.
Barry: Cisco?
Cisco: Yeah?
Barry: Do you have the cure for Caitlin?
Cisco: Yeah, Ray and Gideon did most of the work.
Barry: Are we all prepared for whatever happens tonight.
Everyone: Yes.
Barry: And no matter what happens, no matter what we lose, we will stop Savitar.
Everyone nods their head in agreement.
Later that night, Savitar and Killer Frost came for Iris, and everyone was waiting for them.
Savitar: Hello Iris, the time has finally come for you to die.
Barry: You aren't getting her, not now, not ever!
Savitar: Are you sure? What can you do to stop me?
Sara: Snart, you aren't a killer, not anymore!
Savitar: You don't know what I am, I have experienced more suffering than even you can imagine, Sara!
Sara: Do you remember that time we fought Savage during the Cold War, he captured half the team, Rip said that if we couldn't save Stein, then I would have to kill him, but you talked me out of it! You said that there was always another option!
Savitar: Do you remember what I told you in the Vanishing Point?
Sara: You said that I had a problem with killing people, and that you didn't, but if that were true, you would've shot me, right then and there.
Savitar: I may have acquired feelings for you during our time on the Waverider, but this isn't the Waverider.
After he said that, he grabbed Iris and sped off, Barry ran after them, and Killer Frost trapped the Legends and Wally in a barrier of ice, leaving Cisco as the only one who could fight her.
Cisco: Why do we have to keep fighting?
Killer Frost: We're on two different sides, this kind of thing is unavoidable.
Cisco: Well, I have something that could help you.
He pulled out the needle with the cure.
Killer Frost: I'm not going back to being Caitlin Snow!
Cisco: We'll see about that.
Cisco shot her with a vibrational burst and she laid on the ground, unconscious.
He went over to inject her, but she stabbed him in the leg.
Cisco: Ahh! What is it with you stabbing people in the leg?
Killer Frost: I told you, I'm never going back to being Caitlin Snow.
She froze the vial of the cure and threw it into the ground, smashing it into a thousand pieces.
Cisco: No!
Killer Frost: See you later Cisco.
As soon as she left, the Legends broke out of the ice.
Ray: Where's Caitlin?
Cisco: She's gone, and she destroyed the cure.
Ray: We have to find Barry, can you vibe him?
Cisco: No, I'm too disoriented.
Barry followed Savitar to the place he saw when he first went to the future.
Barry: Don't! Don't do This!
Savitar: Finally, I will be free of you!
Iris: Barry, I love you!
Barry: Dont say that, I'm begging you, please don't do this!
Savitar: You lose, Barry.
Barry: Noooooooooo!
Savitar uses his retractable blade to stab Iris through the heart, then he ran off.
Barry: Iris, Iris, please, stay with me, stay with me, Iris! No!
Barry starts sobbing.
