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.

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.

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

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.

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.

You survived the destruction because you caused it.

Fitz

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.

Fitz: Well it's not good to keep things to yourself Mack. I know what you're going through.
Mack: Really? You know what it's like to lose control? To be trapped inside your own body unable to tell it what to do? To watch yourself hurt the people that you care about?
Fitz: Yeah.
Mack: I'm sorry buddy.
Fitz: It's okay.

Skye: I keep thinking Trip is going to come see me. Make fun of me for being stuck in quarantine. Call me a goldfish or hamster or something. And every time I wake up, I remember all over again. I just can't believe he's not coming back. He should not have been down there.
Coulson: You both went in for a good reason. To prevent Hydra from starting a cataclysm.
Skye: He was trying to save me.
Couslon: He may have saved all of us. The Obelisk triggered a massive earthquake. Imagine how much worse it could have been if he hadn't destroyed it? He died a hero.

Raina: Your whole life, our whole lives have been leading to this one moment.
Skye: Sorry, I don't buy into the whole this is your destiny thing. We're taking the Obelisk and we're leaving. There are too many lives at stake.
Raina: You've got it all wrong. Whitehall, everyone has got it all wrong. This doesn't destroy, it gives life; new life. We finally get to find out what we become.

I'm not saying this is a good plan, but after all the carving and searching and obsessing; I'm pretty damn curious to see what all the fuss is about.

Coulson

Cal: You have to finish what we started.
Skye: No I don't, I'm not going down there. I'm not going to change or transform or whatever the hell you think is going to happen.
Cal: Why can't you see it's a good thing?
Skye: Maybe it's all the dead bodies laying around or the fact that HYDRA wants it. I'm going to make sure that your Obelisk never gets down into that city. And you're gonna leave. This is your one chance to walk away or I will kill you.
Cal: Okay I'll go, but I'll be waiting for you. After you change no one else will understand. They'll be afraid, change is terrifying. But I'm your father and I love you. I will always love you Daisy.
