Lies! You always lie, brother! [It's an old wound, long buried under time and other injuries, but it feels as fresh now as it did the first time Loki had risen against him. The irony is he can't even remember that moment, only the feeling.]

Just when I think I can trust you, you pull my feet from under me! I think you my brother once more and you turn on me!! [He stomps forward, unsure if he means to attack his brother or not, but needing to take some action before his anger shakes him apart.] Why should I believe you, then or now!?
