He may have been mostly quiet, but when Ash was cracking up laughing during the "viewer questions" task where Mark was being asked why he pretends to be stupid / why he drags Chris around... Mark was properly like
and Ash was just over at the side pissing himself... made that task one of the funniest moments of the season for me.
The same goes for the "Power of Money" task when Ashleigh and Christopher were in the diary room.
