That really isn't reassuring
Thing with this shit is that it ends up colouring one's view of the characters involved whether you go through with it or not, either because the threeway itself is given a voyeuristic spin by making it all about them two characters getting together (would say the only threesomes that aren't guilty of that are Wsan's and the one from Fleep, bless), or because they're just plain set up horribly (that'd be B).
Having said that, Jae'lyn did nothing wrong, possibly ever, and it's that fuckface Daliza who's the bad influence
