Something I just noticed when rereading the last few chapters: in the last page of page 2747, Annie's smile is EXACTLY the same as Paz's smile on page 2769.
I initially just thought that perhaps it was a drawing idiosyncrasy, but now I'm starting to wonder—Paz's smile strikes me as reading as false, or someone who is pretending that everything is OK, given the context of her and Annie's conversation right before, where she says that she's going to Spain and weeps. Therefore, I think it could be reasonable to assume that Annie's smile, the same close-eyed, close-mouthed expression, is also her pretending that everything is OK. Maybe you could interpret it as general unease over what happened between her and Paz—and I think that's a very reasonable interpretation!—but I've been turning Annie's crush over in my head for, oh, the years since Court!Annie confirmed that there WAS a crush. And I think now that perhaps she's been secretly pining after Kat & that they're perhaps endgame.
Do I have anything ELSE to support this? No, not really; I gave up the idea of Kat being Annie's secret crush around the time of the cruise, when Annie seemed so genuinely supportive of Kat and Paz. But I'm just stuck on that smile !
Antimony's expression in panel 8 of page 2747 immediately reminded me of her smile in panel 7 of page 970, which I always interpreted as her non-verbally reassuring another person that a difficult situation has been resolved satisfactorily.
