Well, Thane's going to be pretty annoyed if he isn't put into a command/strategic role, seeing as he was the leader of a mercenary band. So he's probably going to turn down Mindwarp's offer of joining her team if he doesn't get that- especially seeing he regards everyone as too inexperienced or too psychotic to be in such a role. He's not actually interested in being a leader out of pettiness, either; it's just what he knows best, and what he feels he legitimately deserves- he thinks he's a tactical genius (he isn't- although he's still a very good tactician, just no where genius/supernatural levels. He's just able to tell what the enemy is going to do).
He'd probably be okay with only being given full tactical and battle command. He would regard other 'leadership' roles as just self-aggrandising titling.
