Sousa: You worried about losing them too?
Simmons: Not really, I have faith. And mathematics.

Simmons: The jumps and the time we spend in any given time period are getting exponentially shorter. If they keep getting smaller...
Mack: We sink.
Simmons: Metaphorically, yes. For us, that means a jump within a jump, which leads to, honestly, I have no idea.
Sousa: Finally. The scientist from the future and I are on the same page.

Yo-Yo: This plan's pretty thin, May.
May: I'd rather have a thin plan than live through the '80s again.

Deke: Stand back, there's going to be a big surge of electricity. Electricity's dangerous, so.
Sousa: Do I look like a neanderthal to you?
Enoch: I spent time with a tribe of neanderthals. Agent Sousa does not resemble one, he lacks the characteristic brow ridges.

Coulson: I'm happy to see you healing. At least, it feels like happiness. I wonder how many one's and zero's it takes to achieve that fuzzy feeling.
Daisy: Well, yeah, I was lucky. Sousa pulled me out of the wreckage, got us home. I'm glad he's here.
Coulson: That makes me happy, too.

It won't be easy, but I know we'll find some way to be together again. Time, space, it's never stopped us before. And I won't stop trying. I love you.

Simmons

Mack: Nice work, D.
Deke: Thanks, Mack Daddy.
Mack: Nope.
Deke: Roger that.

Deke: You know, he single-handedly demolished the Chronicoms, right?
Coulson: Actually, it cost me both hands.

Mack: Didn't you tell me that dude was shady?
Deke: Yeah, but that was before I found out he had a steady job.
Mack: Doing what?
Deke: Selling coke. Although, I've never seen him drink any.

Deke: So what'd you think? It feels like the crowd really responded to my new material.
Mack: I'm pretty sure that last song was from The Breakfast Club.
Deke: Not until 1985 it's not. Right now it's a Deke Shaw original.
Mack: Deke, this is just like you! You steal something from the future and you pretend you created it.
Deke: Oh, let's not bicker over whether or not those are actually my songs.
Mack: They're not.

Deke: I lost my parents early too. Okay? And I still think about it every day. If you want to talk, I'm here.
Mack: I'm good.
Deke: Wait. Wait, wait, wait, wait, wait! We need a game plan here. What if the Chronicoms are still out there? Maybe that's why we're here.
Mack: You figure it out.
Deke: Mack. Mack! You don't have to go through this alone!

The past is sacred.

Mack

Agents of S.H.I.E.L.D. Season 7 Quotes

Two years in ten seconds. It's like the worst episode of "This Is Your Life" ever.

Coulson

Deke: Navigating the past happens to be my specialty.
Yo-Yo: Last time you got stupid drunk and ended up in jail.
Deke: That's not true. I was pleasantly drunk and it was hilarious.
Daisy: He'll be fine. It's prohibition, so alcohol is illegal anyway.
Deke: It's what? Who would think that's a good idea? Even the Kree let us make our own boot juice.
