I love that there's nothing he can say to her, because IMO that means he doesn't want to hurt her. Because if he wanted to, there are any number of toxic things he could have said right then. He could have gotten snarky like he does with Odin. But he fucking doesn't. Because he can't even try to justify himself to her. The biggest asshole in the MCU isn't an asshole to his mom when he has the chance.
I also love that Frigga has been given sole responsibility for Loki's survival. Like, I can just imagine what that conversation looked like between her and Odin. (Instant headcanon - her not visiting Loki was the stipulation Odin gave her. He spares Loki's life, Loki goes to prison, and Frigga isn't allowed to visit him, and Frigga agreed, probably right away.) I will say, I really dislike that the comic plays it off as Frigga being ~overemotional~ and irrational, I think that she still believes in something no one else does and the writers will somehow have Loki live up to that hope. I get that it's always been a longshot, but now I want it more than ever.
Both prelude comics have had some sort of emphasis on the relationship between Frigga and Loki, and I'm SO HAPPY. I'm also worried about what that means for the movie, like I constantly am, but I think this confirms a lot about their relationship and how Loki feels about his mother that I think fandom has suspected for a long time but never had a real glimpse into.
There was some other stuff in there - like Jane feeling bad that she spent a whole year trying to find a way to reach Thor and she shows him show up on international TV and not even send her a post card. There was something really believable and natural about her "I'm done" response, and I think that's a totally fair response. I'm not sure what that means for The Dark World, but if they can resolve the Thor/Jane relationship in a way that is respectful to Jane, I'll be okay. I'm not 100% in love with the idea of them breaking up a couple I adore and Jane not saving her demigod BF through the power of science, which is why it's not the part of the book that thrilled me.
I do love the fact that Darcy has become Jane's confidante. She's officially way more than Jane's intern, she's her friend, and I think that's amazing.
