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.
Legend, if you can put up with Charleys ugly mug then Ziggys should be easy to put up with.
Charley will get the worst boos ever, much worse than what Ziggy would have got.
One bright side could be one less day on BBLB for Nicky!
