If I remember correctly, I Think he got in a fight with his neighbor too, over a parking spot or something. Something is not right with him, dude needs mental help. Hope he gets the help he needs.He's now beat up his girlfriend (twice), his cousin, and tried to attack some random Pizza Hut worker.
Reading people's comments, what's getting lost in all this is the people around him he's actually physically hurting. Walton's on a path to seriously hurt more than just himself.
It's a sad thing to see, and I hope he turns it around - but it's also very hard to help someone who doesn't think they need help.
