Yo-Yo: You’re going to die.
Mack: Well. Everyone dies. And on that day, we’ll have to answer up there for what we’ve done down here.
Yo-Yo: It’s not God I’m afraid of.

Yo-Yo: You won’t listen! I am in a nightmare, and I’m screaming at the top of my lungs and not one of you can hear me!
Simmons: We hear you!
Yo-Yo: But you won’t *listen*! You all saw what happened, and none of you will help me stop this! [turns to Mack] I’m alone. Even you, even you won’t help me.
Mack: No. You’re not alone. We’re in this with you, but you need to hold it together.
Yo-Yo: There’s nothing holding us together!
Mack: Yes, there is! HOPE! We never give up. We’re always held together by hope! So we cling to it, and we vote. We vote.

Mack [to Yo-Yo]: Talbot killed Kim!
Deke: Very very much!

Mack: When does killing become the only way? We’re SHIELD. We’re supposed to be better than that. None of this would’ve happened if you would’ve just said this “invincible” nonsense wasn’t real. But instead you and Simmons lit a match and now Yo-Yo’s responsible for a girl’s death!
Fitz: I’m sorry, Mack. I really am. But it’s not that simple.
Mack: Simple? Is how you live a good life. Not with your theories or prophesies. It’s following the Good Word and doing the right thing every time. Simple as that.
Fitz: No. Not always, ‘cause there’s lots of instances in history where it was necessary to sacrifice the few in order to save the lives of many.

Coulson: You making some progress?
Mack: Eh. Yeah, it’s coming along, but I gotta say, the idea of the Zephyr flying in space still feels a bit out there.
Deke: Yeah, well, I’m not even gonna be born for another fifty years, so maybe rethink ‘out there’!

Deke [asking for love advice]: Like, you got a good thing going.
Mack: Don’t look at me! Last time I saw Yo-Yo, she lied to me, locked me up, and ran off.
Deke: Coulson?
Coulson: Sorry, bro. Apparently I’m incapable of expressing my feelings or letting people take care of me.
Deke: Well, you guys are useless. It’s lemons, then.

Mack: Well, if the arm fits!
Yo-Yo: So, you’re making arm jokes now? I thought those were off-limits!

Yo-Yo: You can’t protect me forever, Mack.
Mack: Did you ever stop to think maybe you’re alive in the future because I *did*?

Simmons: I’m going to prove I can’t be killed.
Mack: What, you too, Simmons? Do you know how all of this sounds?
Simmons: Like science?
Mack: No. Sounds like you’re detached from reality.

Coulson: Hey, Mack Hammer... Can't touch this.
Mack: Now's not the time.
Coulson: Sorry. Couldn't resist.

Coulson: These things look roomier from the outside.
Mack: It’ll get us where we need to go.
May: Hey, could be worse.
Simmons: True. We could be enslaved by an alien sociopath in a dystopian future.
Mack: Or we could be trapped in a virtual reality fascist state.
Fitz: Or stuck at the bottom of the ocean.
Yo-Yo: Or stopping a crazy robot lady.
Simmons: Or falling out of a plane.
Mack: Fighting Daisy’s mom.
Coulson: Or fighting Daisy’s dad.
May: Or *dancing.*

Tess: We can’t go yet, there are still people in danger!
Mack: Coulson’s on it. He’s rescuing the Inhumans right now.
Tess: But not the dead ones!
