Thor

Thor: "I will not fight you, brother!"
Loki: "I'm not your brother! I never was!"

"This mortal form has grown weak. I need sustenance!"

Jane: "How'd you get inside that cloud?"
Darcy: "Also, how could you eat an entire box of Pop-Tarts and still be this hungry?"

"It's not easy to do what you did. You made my men, some of the most highly trained professionals in the world, look like a bunch of minimum-wage mall cops. In my experience, it takes someone who's received similar training to do what you did to them. Why don't you tell me where you received that training? Afghanistan, Chechnya? No, you strike me more as the soldier of fortune type. Who are you?"

Thor: "Sif, you've done all you could."
Sif: "No! I'll die a warrior's death! Stories will be told of this day!"
Thor: "Live, and tell those stories yourself!"

Jane: "Years of research, gone."
Darcy: "They even took my iPod."
Erik: "What about the backups?"
Jane: "They took our backups. They took the backups of our backups. They were extremely thorough."
Darcy: "I just downloaded, like, 30 songs onto there."

Thor: "Why don't you tell her? How you sent the Destroyer to kill our friends, to kill me!"
Frigga: "What?"
Loki: "Well, I must have been enforcing father's last command."
Thor: "You're a talented liar, brother. Always have been."
Loki: "It's good to have you back. Now, if you'll excuse me, I have to destroy Jotunheim!"

Thor: "You think me strange?"
Jane: "Yes."
Thor: "Good strange, or bad strange?"
Jane: "I'm not sure yet..."
