and leave him in the middle of the Redoran village by himself? I'm guessing he'd last....8 seconds or so.

That would be fun.

He'd probably shut up in an instant if he knew what was good for him.

I actually don't think he would have the balls to start throwing racial slurs around when sorrouned by Dunmer.
He's only like that in Windhelm because he knows the Dunmer can't touch him due to his connections to the
Stormcloaks.

From a technical standpoint, he'd just stand there for three days unless called back, otherwise, he'd return home.

He would sit in the corner of a tavern and say nothing.
