no. B respects the hell out of Jedao but he is so far "above" B in wisdom and general goodness (in his mind) that he's not touchable in that way (no he does not know Jedao is Baby. he would be baffled if he did)
theoretically Jedao knows how to seduce people purely as a matter of tradecraft regardless of his personal feelings, but unlike J1 he has never actually tried it
someday they should talk about it though bc Jedao is like.....he DOESN'T talk about it almost ever and it doesn't usually Show in barge events because he doesn't come over all Killer On Mission, but he also killed a lot of people for the people that made him into a weapon!
On the Sebastian side of things, I wouldn't want to expose Jedao's self-worth issues to Sebastian's utterly bored, un-seduced willingness to sleep with him.
j1 to zyl: ... yeah if he tried he might have been able to but it would have been such a bad idea
