129 Blake's 7 (Orbit - Warlord)

Leaving the others to man the office, Avon and Vila take the company car to a meeting but it breaks down on the way back and they have a very serious argument about who’s going to walk home. Avon apologises with a fancy dress dinner party. But when Tarrant gets caught getting off with a hot punk girl under the coats, his parents are forced to take her home. Coming back in the wee small hours, they find that their hyperactive kids have completely trashed the place!
