As a Smuggler (gunslinger) there was a quest on Tatooine where I swear you could kill Kira (Jedi Knight companion). I forget what it was called though. You and Kira were going after the same thing and you defy her and kill her as well as the bad guy.. It might not have been Kira though, it was a year ago when I was leveling my Gunslinger.
It's not Kira, it's a completely different Jedi
