D'karr
Adventurer
I actually tried the NPC trick. He was playing a rogue, so because he wasn't with them the group hired a replacement.
When I gave him Ricky (yes, Ricky the Rogue, I'm, I'm sorry...) he had the new rogue hide in shadows during combat, and not join in the fun.
Maybe if I was using Fate Points or something similar (spend one of these and you get knocked out instead of killed) then maybe that would have worked. He just never had the character do anything, because he was convinced that I would kill him.
The Auld Grump
You should have killed his character in the tavern, just to prove him right.
