Ben: I leaped into myself in the past.
Addison: And that is still only the second weirdest thing you’ve done today. So, how was the future?

Ian: Tell Ben not to change anything in the past.
Addison: Why?
Janis: Because, if he alters his own timeline, it could create a paradox, or erase someone from existence, or make it so that you two never fall in love.
Addison: What? Why would you help him leap into his own body if those were the risks?

Ian: Why can’t I figure this out? Future Me is just casually writing this thing in some Bladerunner apartment probably wearing a very cool trenchcoat and I still can’t put one and one together.
Janis: Should we get you a trenchcoat?
Ian: Couldn’t hurt.

Addison: So you’re a time traveler?
Ben: Yes, I’m Ben from the future. I leaped in 2022 to come back here and save your life.
Addison: From what?
Ben: A man sent back in time to kill you.
Addison: [laughs] Okay, okay, that’s really good. I mean, it’s literally the plot of The Terminator, but it’s good. Okay, can we please go back and have dinner?

Magic: How much damage did he just do?
Ian: I dunno, but I would say that telling people you’re a time traveler is high on the list of things not to do if you want to avoid a space-time paradox.

Magic: In past leaps, we felt any changes to the original history instantly. Why not now?
Janis: Because we’ve never directly messed with our own timelines before. Until Ben finishes the leap, everything is in flux. The phenomenon is called a …
Magic: Don’t tell me. Nano-wave nullifier? Space-time suppressor?
Janis: Quantum Bubble.
Magic: Of course.

Janis: Best-case scenario, when this is all over, Ben and Addison don’t end up together.
Magic: That’s the best-case scenario. What’s the worst?
Janis: Ben rips a hole in space-time, killing everything that ever was?

Ben: How’d you know she’d shoot?
Addison: Because I would shoot.
Ben: She missed on purpose.
Addison: How do you know that?
Ben: Because you wouldn’t miss.

Everyone that goes to war thinks the universe, God, is on their side. We can’t all be right.

Addison: Hey, so, uh, thank you, by the way, for saving my life and all of that.
Ben: Sorry I went off script and almost killed us all first.
Addison: And almost broke space-time.
Ben: That’s right.
