Raina: Before I met your father I was a lost soul with no clue where I belonged.
Skye: The daughter he never had.
Raina: No, no one could ever replace you Skye. You're all he wants. Be honest Skye, haven't you ever felt lost? Or had that feeling that you were part of something bigger. Like you were special?
Skye: When you say special, what you really mean is alien?
Raina: Is that what you believe? We're human Skye, we just have the potential to be more. But the Diviner, now that is most definitely alien.
Skye: Where do you get this stuff? My father?
Raina: Partly, but my grandmother came from a long line of special people who believed in a story about the blue angels that fell from the Heavens. The ancients called them The Kree.

Simmons: We were in the bottom of the ocean in a storage pod, left for dead and Fitz, he said something that caught me completely off guard.
Bobbie: Ah those three little words.
Simmons: Yes, well no. I mean, not exactly. I barely had a moment to process what he was saying or how I felt about it. Next thing I know he's giving me the oxygen, water's rushing in and he's laying there in the hospital bed so pale.
Bobbie: How long was Fitz in the coma?
Simmons: Nine of the longest days of my life. When it finally broke, he couldn't speak. He just stared at me confused. All I wanted to do was help him. All I wanted was my best friend back.

Tripp: Isn't that in the Bermuda Triangle? 'Cause that would explain a lot.
Coulson: Actually, it doesn't have anything to do with the triangle. We solved that back in the 80's.
Tripp: Ah Atlantis?
Coulson: Try Puerto Rico.
Skye: These white markers represent vertical airshafts that are close to the surface. Possible entry points for the city but most of them are under the ocean floor.
Coulson: Except for one, here, in Old San Juan where we'll enter the underground city. A survey team will test the tunnels structural integrity then locate the temple.
Simmons: And then what sir?
Coulson: We blow the hell out of it.

Christian: I don't understand, what do you want out of all this?
Grant: I want the truth about this one event from my past. Admit you made me push Thomas down the well.

Agent Carter: I've seen all of your home movies. The bodies left in your wake. The girl you caged up. There'll be no second chances for you.
Reinhardt: You must be dying to understand all those items you recovered. They're fascinating no?
Agent Carter: I don't suppose you'll tell me where they came from?
Reinhardt: There's a story, a myth from the east of stars that fell from the heavens. Of blue angels who came bearing a gift for all mankind meant to save the world.

Coulson: We may actually have a shot at finding the city.
Skye: Are you sure it's something you want to dig up?
Coulson: If we don't, HYDRA will. We need to get there first.

Discovery requires experimentation and this experiment will take time.

Whitehall

I was put in charge of the T.A.H.I.T.I. project so those people are my responsibility. If going back in this machine saves even one life, then it's worth the risk.

Coulson

Fitz: He'll recover, he did before. Besides brains never delete files they just lose connections, but there's always a back up. It's just a matter of digging and finding them.
Mack: So you've got back up files too?

Simmons: She had GH.325 in her blood.
Coulson: A T.A.H.I.T.I. patient?
Simmons: Whoever killed her also had GH.325 in their blood.

Skye: You two don't have a single thing in common unless you have some Enya albums you've been hiding.
Coulson: No, nothing in common at all.
Skye: I take that back.

May gave specific instructions, you go on a date with a crazy wall I have to chaperone.

Skye

Agents of S.H.I.E.L.D. Season 2 Quotes

Disappear, become ghosts, that's how we have to live now, in the shadows. To save people even when they don't know it, don't want it.

Coulson

It's not just an 0-8-4, it's the first and all Fury knew about it was the trails of bodies that followed it.

Coulson
