May: They'll never take us alive; really? A little over the top, don't you think?
Coulson: I only had a day to come up with this whole thing. Besides, if I let you write the script no one would say anything.

You survived the destruction because you caused it.

Fitz

Mack: I have visual confirmation. Fury's toolbox is locked in Coulson's office.
Bobbi: Did you manage to wrangle the blueprints from the base?
Mack: Yeah, we're almost good to go.
Bobbi: Okay, I'll make contact soon.

Coulson: You have no memory of who you are?
Lady Sif: I know I am from Asgard, but I do not remember my home there. You tell me my name is Lady Sif, but why I left Asgard, what brought me here to Midgard, why I wear these hides instead of armor; a mystery.
Coulson: One I'll help you solve. I'm sure a clue will turn up somewhere.

Agent May: What about Thor?
Lady Sif: I do not know this word, yet when you say it I want to smile.

Skye: The whole room was shaking. Fitz, the gun in my hand exploded.
Fitz: Aw God.
Skye: I thought that I could handle it, but I can't it's too much. I think we need to tell Coulson what's happening.
Fitz: Hang on, wait until I've analyze...
Skye: I can't control it when I get upset or nervous.
Fitz: I'm running that diagnostic on your blood samples right now. Hopefully when it's done we'll have a solution.

Vin-Tak: Asgardian, well that explains a lot.
Lady Sif: It is true, we do not trust Kree. That is why I am here. When Heimdall saw that one landed on your world, Odin charged me with retrieving him.
Vin-Tak: So you came to pick a fight.
Lady Sif: We know enough about Kree history to be concerned.
Vin-Tak: Well then if you know Kree history perhaps you've heard the tale of Terragenesis?
Lady Sif: Of course, ancient Kree descending on planets altering the inhabitants to fight their war.
Vin-Tak: And Earth was one of them.
Skye: Blue angels who fell from the sky.
Lady Sif: Eons ago the Kree waged a very long war. Casualties were high and they needed more soldiers.
Agent May: You mean cannon fodder.
Vin-Tak: We needed killers. One vicious faction among the Kree genetically modified other creatures' DNA. These modifications can be activated with Terrigen Crystals.
Lady Sif: We know these torturous experiments failed.
Vin-Tak: Not on Earth, here we had to shut them down. This faction had built a city. They brought with them the Diviners, which hold the crystals. Their plans were discovered and thwarted by the better of my kind. Putting an end to that dark chapter of our past.
Skye: Until now.

Coulson: Are you talking about fate?
Lady Sif: I am saying there are tides in the universe that you can not swim against.

Coulson: You agree with her. You think Skye is more than we can handle.
Agent May: Look, most of the time, I believe what I see, you know that but...
Coulson: But?
Agent May: You died. You were brought back, with a map to a city encoded in your DNA. Our team's first mission.
Coulson: We picked up Skye.
Agent May: Last week, we took her to that city. I can't help but remember what Lumley said. Wherever Skye goes...
Coulson: Death follows.

My entire life I've been searching for my parents, and my search ended with answers that are so much worse than I could have imagined.

Skye

Dr. Garner: I haven't worked with S.H.I.E.L.D. in a long while. I moved on for a reason.
May: It's a different S.H.I.E.L.D., Coulson's the director now.
Dr. Garner: Okay, but why me? Is this Skye that bad?
May: She's that good; good agent.

Hill: What does S.H.I.E.L.D. stand for Agent Ward?
Ward: Strategic Homeland Intervention, Enforcement and Logistics Division.
Hill: And what does that mean to you?
Ward: That someone really wanted our initials to spell SHIELD.
