The saddest part is, that Quill has a secret admirerer in BG. When you go to the Bhaal tribunal and defeat You know who, you can find in one of the prison cells the corpse of a young guardsman with an unsent love letter to Quill.
So both lifes get fucked up by Bhaal basically.
And there's a dragonborn bard that mentions being inspired by her which I think only comes up if you killed Quill. I guess sweet and innocent bards just tend to drive Bhaal to violins...
