I agree with the idea that the GM shouldn't force things on my character, though given some of the things he's done in previous campaigns he's run (wherein he basically took my character and made it his own), this is actually a improvement for him. Still, I've already spoken to him about it (mentioning my initial plan for the Leadership feat, of course), and he's pretty much said that it's this or nothing. That said...
I dunno... I think that the GM is expecting me to actively pursue the relationship first, since at this point in the campaign, he's basically stated that the relationship is only a possibility, as opposed to being something established. That is to say, life-saving aside, Vikki isn't really all that attracted to Jesse yet, and I'll have to have Jesse actively try to change that. But there's a problem with that...
The way I see it, Jesse would have a lot of pity for Vikki given her lot in life, but beyond that, I think Jesse wouldn't really like Vikki that much. Vikki's constantly picking the pockets of just about everyone, including not only innocent people but also potential and even established allies, which Jesse would see as selfish and wrong. Jesse would, perhaps, catch Vikki in the act, were it not for the abysmal spot checks I make.
In fact, Jesse has no reason to believe that Vikki is compatible from the perspective of sexual orientation. Vikki has performed "services" for female NPC's in exchange for favors, but Jesse doesn't know about that, and even if she did, there'd be no reason to think it was anything but business.
The fact that your DM has taken over a previous character before and is now not listening to you I have all kinds of warning bells going off.
What your DM is doing is railroading. As a DM I sometimes limit the leadership feat because I think that the party is to big. I will sometimes limit class of a henchman. But to say okay you can do it but you have to use this NPC because I want you to role playing out redeeming her is over stepping his role as DM. If you are not interested in role playing this out the DM needs to accept it.
