Des to his chums. He does a lot of on-line gaming and delves into on-line dating describing himself as a “buff twenty something” when he’s a good deal older and not buff at all. He rarely meets his intended date, thank goodness. Lives with his Mum, which again is perhaps just as well. Nobody ever goes into his room apart from his cat and whatever the cat had brought in. There is nothing he does not know about computers and could probably hack into the Pentagon if he wanted to.
I’ll let you fill in any other details from your imagination, but don’t waste too much time on it, or him.
Thanks to Richard who came up with this name for me and suggested the possible drawing too
