Does anyone know if a KOTOR 2 script is floating out there. I'd like some lines of monologue by the Exile, when he trains Bao Dur, Atton, or those other force sensitives.

You can easily check all the dialogues you want with Kotor tool and tk102's dlg editor . You'll find the tools here: www.starwarsknights.com/tools (Kotor tool also has a dialogue editor: you can use it to view dialogues but do not try to edit Kotor 2 dialogues with it or you'll loose important information when you save as it is not yet fully compatible with kotor 2)
