Loki: The Casket wasn't the only thing you took from Jotunheim that day, was it?
Odin: No. In the aftermath of the battle I went into the temple and I found a baby. Small for a Giant's offspring, abandoned, suffering, left to die. Laufey's son.
Loki: Laufey's son?
Odin: Yes.
Loki: Why?

You were knee-deep in Jotun blood. Why would you take me?
Odin: You were an innocent child.
Loki: No. You took me for a purpose. What was it?... TELL ME!
Odin: I thought we could unite our kingdoms one day. Bring about an alliance, bring about permanent peace... through you.
Loki: What?

Odin: But those plans no longer matter.
Loki: So I am no more than another stolen relic, locked up here until you might have use of me?
Odin: Why do you twist my words?
Loki: You could have told me what I was from the beginning! Why didn't you?
Odin: You're my son... I wanted only to

protect you from the truth...
Loki: What, because I... I... I am the monster parents tell their children about at night?
Odin: [unwell] No! No!
Loki: You know, it all makes sense now, why you favored Thor all these years, because no matter how much you claim to love me, you could never have a Frost Giant sitting on the throne

of Asgard!
[an overcome Odin collapses]
Loki: Guards! Guards, please help!

[while interrogating Thor, Coulson steps out for a moment...]
Thor: Loki. What are you doing here?
Loki: [as a SHIELD agent] I had to see you.
Thor: What's happened? Tell me, is it Jotunheim? Let me explain to Father...
Loki: Father is dead.
Thor: What?

Loki: Your banishment, the threat of a new war... it was too much for him to bear. You mustn't blame yourself. I know that you loved him. I tried to tell him so, but he wouldn't listen. It was so cruel to put the hammer within your reach knowing that you could never lift it. The burden of the throne has fallen to me now.
Thor: Can I come home?

Loki: The truce with Jotunheim is conditional upon your exile.
Thor: Yes, but... couldn't we find a way...?
Loki: And Mother has forbidden your return. This is goodbye, brother. I'm so sorry.
Thor: No. I am sorry. Thank you for coming here.
Loki: Farewell.
Thor:

Goodbye.
[Loki leaves, just as Coulson returns]
Agent Coulson: [having heard Thor] "Goodbye?" I just got back.

[Loki appears in Jotunheim]
King Laufey: Kill him.
Loki: After all I've done for you?
King Laufey: ...So you're the one who showed us the way into Asgard.
Loki: That was just a bit of fun, really. To ruin my brother's big day, and to protect the realm from his idiotic rule for a while longer.

King Laufey: I will hear you.
Loki: I will conceal you and a handful of your soldiers, lead you into Odin's chambers, and you can slay him where he lies.
King Laufey: Why not kill him yourself?
Loki: I suspect that the Asgardians would not take kindly to a king who had murdered his predecessor. Once Odin is

dead, I will return the Casket to you...
[Laufey stands, his expression hungry]
Loki: And you can return Jotunheim to all its, uh... glory.
King Laufey: I... accept.

[about the burglary]
Thor: The Jotuns must pay for what they have done!
Odin: They have paid, with their lives. The Destroyer did its work, the Casket is safe, and all is well.
Thor: All is well? They broke into the weapons vault! If the Frost Giants have stolen even one of these relics...
Odin: They

didn't.
Thor: Well I want to know why!
Odin: I have a truce with Laufey, king of the Jotuns.
Thor: He just broke your truce! They know you are vulnerable!
Odin: What action would you take?
Thor: March into Jotunheim as you once did! Teach them a lesson! Break their spirits, so

they would never dare try to cross our borders again!
Odin: You're thinking only as a warrior.
Thor: This was an act of war!
Odin: It was the act of but a few, doomed to fail.
Thor: Look how far they got!
Odin: We will find the breach in our defenses and it will be sealed.

Thor: As king of Asgard...!
Odin: BUT YOU'RE NOT KING! Not yet.

Loki: What troubles you, gatekeeper?
Heimdall: I turned my gaze upon you in Jotunheim but could neither see you nor hear you. You were shrouded from me like the Frost Giants that had entered this realm.
Loki: Perhaps your senses have weakened after your many years of service.
Heimdall: Or perhaps someone has

found a way to hide that which he does not wish me to see.
Loki: You have great power, Heimdall. Did Odin fear you?
Heimdall: No.
Loki: And why is that?
Heimdall: Because he is my king, and I am sworn to obey him.
Loki: He was your king. And you're sworn to obey me now. Yes?

Heimdall: Yes.
Loki: Then you'll open the Bifrost to no-one! Until I have repaired the damage that my brother has done!
