You can't have both fish and bear's paw

Ryan Phan: Great. I have to manually re-enter all this code.

Tree Gelbman: Okay, how long?

Ryan Phan: Six, seven hours.

Tree Gelbman: Ryan, look at me. I am on borrowed time here. Understand? Get it done.

Ryan Phan: Uh, yeah, I'm on it.

[Tree leaves. Carter runs after her]

Carter Davis: Tree, wait up.

[Tree continues walking away]

Carter Davis: Hey. Are you sure about this?

Tree Gelbman: Of course I'm sure.

Carter Davis: Okay, well, what about the killer?

[Tree stops]

Carter Davis: I mean, you said people are gonna die tonight. If you close the loop and we don't help, then they're dead for good, aren't they?

Tree Gelbman: [firmly] I have to stay alive. I can't go back to that hospital. It's way too risky.

[Tree starts walking away]

Carter Davis: Okay, so that's it? You're just gonna walk away and let a bunch of innocent people die?

[Tree stops and returns to face Carter]

Tree Gelbman: People die every day, Carter. I can't be responsible for everyone, okay? I know how selfish that sounds, but it's true.

Carter Davis: [disdainfully] Yeah, no, that sounds incredibly selfish. Are you serious?

Tree Gelbman: [shakes her head tearfully] That's not fair. You have no idea how hard this is for me. I don't want to have to choose between you and my mom, but I have to.

Carter Davis: What do you mean, "choose"?

[Tree hesisates for a moment]

Tree Gelbman: Carter, we're together in the other dimension.

[Carter gapes]

Tree Gelbman: I woke up in your bed every morning, just like this morning. I did it over and over and over again until I fell in love with you. But that version of us is back there, and my mom is alive here. So I've made my decision.

Carter Davis: Wh... what if you're wrong? Huh? What if you're wrong? What if this isn't the life that you're-you're supposed to have?

Tree Gelbman: So, what? I'm just supposed to go back to some dimension where my mom's dead?

[Tree shakes her head, choked by tears]

Tree Gelbman: I can't. I can't lose her again.

Carter Davis: [quietly] You already did. And none of this is real if it erases that. You're just... you're living someone else's life that doesn't belong to you. Y-Your pain, th-that loss, that's... that's what makes you you. But you have the chance to do something other people only dream of.

Tree Gelbman: What?

Carter Davis: You can say goodbye.

[before Tree can answer, they hear Danielle calling Carter "Yoo-hoo!". She approaches]

Tree Gelbman: Your girlfriend's calling you. Better go.

[Tree walks away]

Danielle Bouseman: What's her problem? She just ditched our house meeting.

[Carter does not answer. His eyes are fixed on Tree, as she getting further from them. Danielle notices that and snaps her fingers before his face]

Danielle Bouseman: Hello? What were you guys talking about?

Carter Davis: [lies] Nothing. We were just... we were going over school stuff.

[Tree is sitting in her parents' car. They drive away from the campos. Tree feels gloomy. She has second thoughts about her decision to stay in this dimension]

Julie Gelbman: [turns to Tree] Hey. You know what I'm craving right now?

Tree Gelbman: What?

Julie Gelbman: One of those giant cinnamon rolls from that bakery in Morro Bay.

[Tree looks puzzled, since she does not remember anything like that]

Julie Gelbman: From our birthday last year. You don't remember? You ate two of them.

Tree Gelbman: [whispers] That wasn't me.

[Tree realizes Carter was right; she does not belong to this dimension]
