Duck and Cover

Cody, in front of the Cat's Paw. I know you can give him nuka-cola or food and he runs away, and if you try to give you booze he runs away, but is there some other purpose this NPC serves?

Yes later, he tells you who stole your car, and then what's his face sells him a farm, he reluctantly accepts.

I didn't know that. I always ended up slapping Jules around until he spat out the info...

Make sure you take off your power armor when you talk to cody, or you scare him off.

EDIT: I know you can offer him Jet, some day I'll stock up with every drug I can think of, and test them out.
