EastEnders - Dennis warns Ash off Sharon

At the party, Vicki tells Dennis that Joanne was asking about him, and Dennis asks Vicki why Sharon's talking to Ash. Vicki says he's a DJ, so probably the club. A few minutes later, Dennis talks to Ash and is incredibly jealous, starting off aggressively with "stop sniffing around her - she's already taken". The DJ backs away in surprise.

This was taken from an episode of EastEnders on Thursday 5th June 2003.
