Is it me or do they keep changing his hairstyle?

Anyone know when he leaves our screen and for how long and when does Rob get found out.

His hairstyle reflects what state he is in with regards to alcohol intake, I reckon

He looked awful last night! He had a sort of side sweeping fringe....what with that and that awful goatee beard, he's starting to look like an unwashed illegal immigrant just got off the boat!

I just hope that when he returns he'll come back clean shaven again....

Judging by what he is going through I don't think Peter cares how he looks.
