I know it's a minor thing to some fans and fic authors, but it gives me a whiplash every time I see Loki being called "Laufeyson" in fics that are specifically based in Asgard, especially when his Jotun heritage is kept hidden or simply not discussed.
It's even funnier when it's a pre Thor 1 fic. (Like why is the Asgardian prince being addressed by the name that suggests he's the son of the Jotun king, who's Asgard's long time enemy? He should be called Odinson not Laufeyson.) He most certainly won't call himself Laufeyson, or let anyone else call him by that name in a setting where his Jotun origins aren't common knowledge.
Moreover, post Thor 1, it's a pretty big deal for Loki, to be called by the name of the father he has no connection with, who, as far as he knows, abandoned him as a baby, who he killed himself, and lastly, who belonged to a people he was taught to hate. He may learn to accept that heritage, slowly, over the course of time, but he most certainly won't call himself Laufeyson. Even in The Dark World, he called himself "Loki of Jotunheim" and not Laufeyson when he was trying to lure the dark elves into trusting him with handing over Jane.
To some extent, the same logic applies to the name Odinson as well. But Loki uses it based on convenience. Plus it's the name everyone knows him by in Asgard, and there's no reason for him to reject it pre Thor 1, or even afterwards. Unless it's someone really close to him or someone who understands his strained relationship with Odin, he won't bring it up.
What he usually goes by, post Thor 1, is Loki of Asgard, even though, in his perspective, he doesn't belong there either. But it's a connection that most people know of, hence he uses it based on that.
Idk where I'm going with this post, just sharing my annoyance I guess. I know that post TDW stuff is also on shaky ground regarding this issue, but I'm not going there. I don't even consider the series as canon.
