Ziggy is a good person who just hasn't got the sort of personality you need to be able to cope with life in the house. He tries too hard to do the right thing, is far too concerned about what his family think as they are obviously very important to him and he misses them, and he's got a habit of saying the wrong thing and not explaining himself properly. It's better for him to just leave and take the experience for what it was.

Or rather he hasn't got a personality full stop. He keeps throwing in the line about what his parents would think if they were watching, but he's been up to all sorts of shenanigans soon after he's said it. Pointless?
