Leo Fitz: I couldn't live if you didn't.
Jemma Simmons: I feel the same way. There has to be another way.
Leo Fitz: You're taking it.
Jemma Simmons: Why would you make me do this? You're my best friend in the world!
Leo Fitz: Yeah, and you're more than that, Jemma. I couldn't find the courage to tell you. So please. Let me show you.
Jemma Simmons: I like to think about the first law of thermodynamics. That no energy in the universe is created and...
Fitz-Simmons: None is destroyed.
Jemma Simmons: That means every bit of energy inside us, every particle will go on to be a part of something else. Maybe live as a dragonfish. A microbe. Maybe burn in a supernova 10 billion years from now. And every part of us now was once a part of some other thing. A moon, a storm cloud, a mammoth...
Leo Fitz: A monkey.
Jemma Simmons: A monkey. Thousands and thousands of other beautiful things that were just as terrified to die as we are. We gave them new life. A good one, I hope. It's fitting we're down here together, Fitz. This is where all life began. On our planet, anyway.
Leo Fitz: Ward, look at me.
Jemma Simmons: Think about this!
Leo Fitz: Ward, just turn around! Don't do it! Don't do it, Ward! Okay, you don't have to do this.
Jemma Simmons: Ward!
Leo Fitz: You don't have to. You have a choice. Ward, look at me! I know that you care about us, Ward!
Grant Ward: You're right. I do. It's a weakness.
Leo Fitz: Ward, please. I need to understand.
Jemma Simmons: You need to accept the truth, Fitz. He doesn't care about us. About anything.
Leo Fitz: No, I don't believe that. We're friends, aren't we? We've been friends. We've had laughs together. I know that you're a good person, Ward. And you can choose right now to be good. It's a choice.
Leo Fitz: I thought HYDRA was defeated after World War II.
Phil Coulson: It was. S.H.I.E.L.D. was founded in the wake of that victory.
Leo Fitz: And now they're back?
John Garrett: HYDRA always comes back.
Phil Coulson: Cut off a head, two more will take its place.
John Garrett: Is it a head? I thought it was a limb.
Leo Fitz: You know, that's the one drawback of graduating three years early. We never got to pull any freshman pranks on anyone else.
Jemma Simmons: Mm. Fitz. Skye never went to the Academy. She's a freshman.
Leo Fitz: A wide-eyed little freshman.
Jemma Simmons: And being pranked is an integral part of becoming a S.H.I.E.L.D. agent.
Leo Fitz: Well, mandatory, really.
Jemma Simmons: Why not give her the full S.H.I.E.L.D. Academy experience?
Leo Fitz: It would be unjust to deny her such a thing.
(Simmons is isolated in a room, Fitz runs inside...)
Jemma Simmons: No! Uh... You can't be in here!
Leo Fitz: Too late. It's done. Just try and do your best to keep your hands off me, yeah?
Jemma Simmons: Fitz, I don't know what you think you're doing, but...
Leo Fitz: I'm doing what we always do. We're gonna fix this. Together.
Phil Coulson: What's Fitz doing out there?
Jemma Simmons: He detected a strange energy coming off the body.
Phil Coulson: He's afraid of it, isn't he?
Leo Fitz: It's the smell!
Jemma Simmons: There's no shame in it, Fitz. It's perfectly natural to be afraid.
Leo Fitz: No, the only thing I'm afraid of is putrid, decaying flesh corrupting my pristine workspace. Do you remember the last time you brought a dead thing into the lab?
Jemma Simmons: Oh, not the stupid cat again!
Leo Fitz: The cat!
Jemma Simmons: And it's our lab, Fitz, not your lab!
Leo Fitz: Tell him about the cat. You left his liver next to my lunch!
