3 searches: Steve/Bucky, and 2 Loki-centric
I think it was a modern Bucky/CA Steve story: they save each other from bad dates/uncomfortable situations? I think it was first Steve saves Bucky from a bad date, then Bucky saves Steve from one and invites him to hang out with the Commandos (who are all modern too).
Events of Thor film went differently, and Loki did not kill Laufey. Later, he goes to meet with him, and asks if he had a son that was killed/kidnapped, and then reveals that he is that son... it was a longer story that had an entirely different focus I think, I just remember this one scene.
Any Loki-centric searches where he is raised in Asgard as in the canon, but then interacts with the Jotuns a lot, in a peaceful way? Reconnecting with his roots, that sort of thing.
