[Colonel Flagg]

Wait a minute, Sappy - your friend was thrown out for connecting a computer to teh interwebs, right? And now his legal guardian (I'm assuming a lot, since you don't mention it, but step-dad was married to mom, so that makes it more than likely) threatens him with bodily harm for coming back to get his clothes and other possessions, right? And he's legally a minor child, right?

Three words - get a lawyer.
