I'm on my 11th PT, and I still get things I never heard before, especially from the companions. The Morrigan/Wynne things happens if you spend too much time discussing your choice with Morrigan and trying to stay on her good side. If I'd been thinking, I wouldn't have added her to the group until after I recruited Wynne.
That happened to me accidentally the first time I brought Morrigan to the tower as well.
Gee, Wynne, you really want to pick a fight when demons are attacking the tower? Did you forget you're the only one keeping that barrier up, so we end up killing each other, there will be nothing stopping the demons from marching in here and killing those innocent kids? Get yer danged priorities straight!
It makes me really glad they cut out the whole thing where if you were a Blood Mage, you ended up forced to fight the Templars and First Enchanter, even if they just said they owed you for saving the Circle and you pointed out that legally Wardens are allowed to use it! the Circle Tower would have been incredibly frustrating if I had to keep being forced to kill people just because they were ungrateful, dogmatic morons!
Makes me think that if you did the Tower first, the Zevran recruitment would have gone a lot differently.
Alistair: You want to bring the assassin with us as well?
Mage Warden: Look Alistair, we need people. You saw how FUBAR the trip to the Circle Tower went.
Alistair: That's because you kept killing people we wanted to recruit!
Mage Warden: That was their fault! So I used Blood Magic to rend people apart, at least I don't complain about rescues I don't like! That's just rude!
