Loki loved his mother so much he acknowledged himself as Jotun — the unclean truth inside him that he’s been trying desperately to disprove and scrub out since the moment he first discovered it and lost his sanity — so that he could avenge her death.

I’m editing to add this: You can see him suck in a breath after he says “Jotunheim” as though it physically pained him to say that word. Ugh. I’m going to have Loki feels all day now.

Star Trek can make as many new series and movies as they like, and still nothing will ever truly beat the golden awkwardness of this one shining minute of dialogue.
