It’s fascinating the change in expressions from the two gifs. In the first one he’s determined and sets out to help Thor.
In the second, he realizes that his act of heroism didn’t matter: Kursed lived. Then there’s that look of resignation, bordering on despair, as he realizes what’s coming next.
Loki knows he’s going to die. Just when he made the choice to fight to live (you can see when Thor saves him from that mini void explosion that he’s started hoping -even wanting- to live through this) it’s gone.Yes. This.
It’s kind of even worse when you consider that Thor saved him from death so that he could die to save Thor. You can totally see Loki playing it that way in his head. He’s always secondary to Thor. Even when it’s his own choice, he makes it that way. Always.
