I beat Dragon Age: Origins, and I'm tempted to go straight into Dragon Age II with that save file instead of dealing with Awakening, Golems of whatever and Witch Hunt. (Morrigan is my Warden's love interest.)
I can answer for Awakening. Jack ****. Regardless of what happened with Anders, he comes back as a homosexual and constantly berates Hawke about wanting to sleep with him. And regardless of your actions (ok it may be avoidable, as people have been saying, but I highly doubt it), he tries to rape you in one scene. So that's what's up.
If Mittens saved baby penguin based on his beliefs, and Mitten's beliefs are not in his direct control, does Mittens really have free will? ~Maraka
