Actually, I'm surprised he actually had it in him to give her that teddy bear. He at least knows "cute." Sexy, I don't think so.
I mean if he and Duo ever did talk about THAT, it might go something like
this. And if he ever got post-coital, it would probably go something like
this.
Full version of the latter to be posted on Feb 12. xD
EDIT: I'd give Sumisawa bonus points if seduction is part of the reprogramming and Relena's just "Who the fuck are you?" xD
