*purrs* Ooh, I love it! The steam of consciousness works great for it too.
(and running out of bullets, always out of bullets)
BRAWHAHAHAHAAHAHAA!!!! *dies laughing at that*
Seriously, I do love this. I love the way you portray Trowa's feelings toward Quatre, what with the PSTD, and Duo's dancing in the rain, drunk as hell. I love the bit about him never being sober again and the kissing with 'I hate this fucking world', and it's so perfect for them - that sense of anger and hate and a pinch of despair at the world for what they went through. But then also that defiance and teeny bit of hope that lets them survive. I also love the punching and Rocky reference. XD
One itsy, bitsy, minor thing that might not even apply: does Quatre drink? I seem to recall a reference to him not drinking alcohol towards the end of the anime, although maybe I'm remembering wrong and it's just fanon? Some comment about non-alcoholic champagne... If he's a Muslim, then he probably wouldn't drink alcohol.
