Mark attends a work conference and in the process makes a new friend, Alan Johnson, which upsets the 'El Dude' partnership. This forces Jeremy to consider who could replace Mark as flatmate and best friend. Super Hans is the potential replacement, but he doesn't match up as well. Mark grows a moustache, like his new hero, Johnson whilst Jeremy is haunted by flashbacks to 'the one bad thing' that happened when he was wrecked with Super Hans. (thetvdb.com)
