After Loki was dragged back to Asgard, it was decided that he’s suffered a complete psychotic breakdown and isn’t mentally sound enough to stand trial. Instead his magic is bound and he’s put into the care of the healers. He has free run of certain parts of the palace, but he’s constantly accompanied by a small army of guards and caretakers, who can step in when he has another psychotic episode. (I’m working on the premise that Loki did actually have a serious mental breakdown).
Some time later Jane gets to visit Asgard. She’s warned that ‘the mad prince’ is skulking around somewhere, but she’s still shocked to suddenly run into him one night in the library. The two strike up an unlikely friendship.
Somehow Jane and Loki being friends who bond over astronomy and physics/magic works and it’s touching even though there’s cultural misunderstandings and Loki is still shaken up by the coercion/control/brainwashing/fractured sanity that lead to the events of the Avengers. They spend a lot of time in the library and constantly tell each other their feelings and it’s just… Dammit Loki, you aren’t supposed to end up being an honorary science bro and pulling a Tony and trying to convince Jane to stay in Asgard so you can be science BFFs and feel appreciated for your magic. Aside from that unlikely friendship there’s a heap of wonderful world building, which doesn’t try to handwave science too much. Then there’s a garden which I’m going to call the Khloidanikos because it’s a thaumaturgical piece of architecture and Frigga tends to it and it sounds so pretty. There’s also poetry as therapy and plenty of interweaving history and folklore into this fic’s universe.
It’s long though, I haven’t read it all yet and it is a WiP, but Loki being a science bro just delights me.
ETA: Now complete and on AO3. Jane completes her version of the Bifrost on her own terms and everything is glorious.
