Re-recruiting Dorn? Possible spoilers...

So I've recently learned that the Elven Chainmail is finally available, but only through Dorn's quest. I know I could just add it via console, but I'd have more fun playing to get it.

However, I've already met Dorn at the Friendly Arm, and then participated in the ambush near Nashkel. I'm playing a basically good party, so I sent him packing, and he wasn't happy. Now, if I talk to him at the Friendly Arm, he more or less tells me to watch my back and get lost.

Anything I can do to recruit him at this point, or do I need to just resort to adding the armor via console?

Thanks!!
