AB can't deal with Lavon's hotness in that tux, is the subtext here. The actual text is that Lemon is still really mad at her, and she's sad. The thing is, I feel empathy for AB here, but also if I were Lemon and my best friend slept with the man I was madly in love with, I would not react well to that. I am Team Lemon, with a few caveats. I am also team AB's Dress, though.
