This is based on the events in Thor 2 - if you haven't seen it yet, you may not want to read the small description, though I guess everyone knows by now.
Loki says he does not care. He says it to everyone else, to the guard delivering the news and looking so sorry and pitying, to the other prisoners surrounding him in his pathetic little cage, and he will later repeat it to the man who is decidedly not his brother even though he has memories to disprove that.
Most of all, he repeats it to himself again and again and again that he does NOT care.
But he knows he is the biggest trickster in this realm, in all realms. And who is he, trying to kid the greatest kidder.
So he retreats into his own darkness, putting up the front that is fooling everyone but the man who is not his brother - he did learn something after all. And when he retreats into himself, he cannot deny that his best memories are of her. The only person who still loved him after everything. And now she's gone.
These parts of the movie were breaking my heart, I am still choking up slightly thinking about them. I wanted to hug someone desperately though I guess the guys next to me wouldn't have approved though there were sniffles from his direction as well.
On another note, anyone else wonder how on earth (or on Asgard) they went on the potty in these prison cells? Is it a form of torture - having to do your business in front of everyone? I mean seriously. I can't stop wondering about this.
