while my gut reaction is, generally speaking, Takaba, who? Especially, especially, when Feilong is in the shot, I have given it some thought and:

it's more just how the characters are handled

dude, what are you talking about? because unless i'm getting it wrong--which is possible--Takaba have finally figured out that:

a. if he's going to be a plaything ANYWAY, he might as well be Asami's plaything (considering the crackpipe, i can't say i blame him. at least asami seems to be laying off his toys lately)

b. he's a slut (d'oh) and what he *really* wants is a threesome. that he also prefers sex with Asami to sex with Feilong. now, you know i love Feilong, you know i do, but um...not the bestest seme. srsly.
