You may find him a drain, but by definition he is a character. Most of the discussions on these forums and on social media this series have revolved around him. That is a good thing and one which shouldn't be discouraged. And if there were far better characters in there, they would be getting an edit! You can't say things like that when all we have to go off is the edit itself, we don't have live feed anymore so it's impossible for anyone to speculate on such things
You are letting your personal dislike of him (which I can understand, I'm not saying I like him as a person but there's a difference between people and housemates) get in the way of the logical argument that he should stay for the benefit of the series
