I like how the infirmary kiss in Longkhong is a soft, chase kiss because it's meant to be the ~Pure Love Kiss~ the Straight Fangirl wants them to have, but when the magic's ~corrupted~ and they're All Over Each Other later with more realistic passion she's HORRIFIED. Nicely done.
I maintain my theory that they WERE actually into each other and were on their way to realizing it but they were Not Very Introspective with a dose of Internalized Homophobia so they likely never would have accepted it even if they noticed and would have ignored it and moved on.
Which is why in MY fic, I put them in a parallel universe and changed some environmental influences on them because I'm not going near their terrible messy canon selves. [cough]
