I don't even know him 

I don't.

Yep, and you never will either as he's hiding the true him.

Don't we all though? 

Hey, you're supposed to be in bed Sprout

  Ok, ok, I'm a gawn 

If he's going to hide the real him then at least be interesting, he cant even manage that.

He's a bit meh, wouldn't mind if he went

I don't think he's hiding anything - there's nothing to hide.

A personality-free zone.

I think Cosmo is right, there's nothing there at all... he's just boring. And this whole "he's too nice" thing gets right on my nerves though, gormless he may be, it sounds ludicrous that the whole house has targeted him for being "nice".

It was the same with Dexter and Michael, both easy targets. All of them rarely want an argument.

On a side note, I thought it was piss funny how Callum talked about going stateside 'until the PR dies down'

I wouldn't say I like him but he's near the bottom of my Dislike List.

I like him, I think he's a genuine guy.  This whole 'too nice' thing reminds me of the attacks on Rachel Rice for being too nice and sitting on the fence.  Dan on the other hand is always saying what a nice guy he is and in my opinion he is totally self deluded.

His mother gave the game away, on BOTS, when she said that he loves an argument and she couldn't understand why he was behaving like he is.

I believe his VT was more like the real Callum.
