So-- question. 

This is the first time in a while I've seen a post with at least two sentences dedicated to Steven's thought process. There was absolutely no mental explanation for why Steven took the horse when the old man clearly permissed Abel to take it.

Now, obviously because you never mentioned it you can make up whatever explanation you want for Steven's thought process, but for curiousity's sake I have to ask:

Is Steven really that stupid or was he just being a hugely conceited dick? 

Honest question. It's one or the other and Abel himself is just making guesses. I was just wondering which one it actually was-- especially since his character sheet doesn't mention anything about him being stupid OR a dick. So this must be a new attribute. For story telling purposes, I would just like to mentally note it for the future.
