Well, you could ask her what she thinks about the other party members or the party as a whole. Also some talk about the croups reputation could be in order. For an example: Imoen: "Hey CHARNAME do you have a second?" CHARNAME: "Sure, whats up?/ What now?/ GET LOST BRAT!/ *grunt*"
(If you have been bad)Imoen: "Watcha problem? Whydaya keep hurtin people?"
etc etc etc.
Regards.
Imoen does Jan annoy you too or am I hearing voices?
Imoen how do you feel about having Sarevok in the party?
Hey, are you alright? You look kinda...odd...
How does it feel to die? I mean, I have never even been resurrected.
Imoen, that you was caught by the cowled wizards is a testament for you being weak. That, and your constant giving to the poor and suffering. Why don't you start being resonable and think about yourself?
