All three. No witnesses, never any witnesses.
Ditto! LOL
The first time, I also killed the old hag (reminded me of my evil step mother, too hahaha). One time I killed the Khajiit, because he threatened to find and kill me. PSH.
Then on my Shadow Warrior toon, I didn't even ask any questions, I just aimed with my bow and BAM BAM BAM I killed them all (the mercenary was so whiny, too!)

EDIT: Did I say I called the Argonian? WTH was I smoking hahahahaha
