Spare me! [Loki recognizes her voice, if only from passing. He isn't one to mix up siblings, no matter how similar they might be. He is also not in the mood.]

Oh yes--[And the timbre of his mockery here is bitter, just on the edge of grief.] You love her, and if I don't do my job well you'll punish me terribly, yes? Take my life for hers? We're already trading in those.

[There's a very tense pause as he draws an audible breath and holds it. When he speaks again it is with forced calm.]

You'll have your sister back.
