Liz: You're gonna find that cure. And then you're gonna find your way back to Allie. I don't believe any situation is hopeless.
Shivani: That's what I like about you, Liz. That optimism.

I know Alex is busy, but you would think he would check in.

Michael [to Maria]

Clyde: Bonnie is powerful but unpredictable. And without guidance, unpredictable things tend to happen.
Michael: Well, should we stop wasting fresh air and go find her?
Clyde: I don't care whose son you are, if your little chats with Bonnie hurt her in any way, I will destroy you.
Michael: All I want to do is help.

Tezca: You're wasting your potential trying to save one small town when there's a whole planet that needs saving.
Max: That is not my responsibility.
Tezca: It's your destiny! Ophiuchus has foreseen it.
Max: I don't care about Ophiuchus!

If we put an end to this, we'll both be free to move forward.

Michael [to Bonnie]

Clyde: Humans are obsessed with the illusion of happiness.
Michael: I am intimately familiar.

Isobel: Santa Fe. Isn't Eduardo from Santa Fe? Has he ever mentioned a daughter?
Kyle: No, but it's not like my family doesn't have a history of secret daughters.

Michael: So, what are you hiding from Liz? Cuz I can feel you humming. And you're lucky that miss centrifuge can not.
Max: Do you tell Alex everything that's going on with you?
Michael: I was trained in the art of trust issues for twenty-some years, Max. So, no, I do not. But I regret it. Every single time I don't let him in.

Bonnie: I spent my whole life believing everything that they said. But earth is like...it's proof that things can be different.
Michael: You know it's good to ask questions. Helps you figure out what you want. Where you belong.
Bonnie: Well that often gets me in trouble.

Michael: I'm here now. I will protect you.
Bonnie: I don't know that you can. But I love that you'd be willing to try.

Cameron: You're in love.
Isobel: It's horrible, Cameron.

Eduardo: Let me ask you this. Do you think they're all bad?
Michael: No, I think some of them are just lost.

Cameron: Well, as much as I wish this was a good old-fashioned laugh and get lit, I've called you to help solve this odd little bank job.
Max: Me? Why?
Cameron: Cuz I think you and I might be the only people who can crack this case. I think this heist was committed by aliens.

Make yourself at home, okay? It is yours after all.
