You don't have to switch to the default if you want, it's just better for testing stuff. Maybe use that to figure out what's wrong with the PAIN2 animation, aggression, and such, then change them in Tale of Vengeance.
I looked at a couple of character files and everything seems right. Really can't figure out why PAIN2 isn't working for Poison. What I would probably do is drop Poison into the default BOR mod, change her aggression to something like -300 (as well as 0 and 300 for comparison), and then see if you can narrow down what's going on with those two problems first.
Hope this isn't too discouraging! I didn't mean to sidetrack you with this, just do what you like and people will like it. :)
