Kat (Jessie Wallace) rejects Mark's advances when he tries to flirt with her at The Vic, but Alfie later annoys her by adopting a 'treat her mean, keep her keen' attitude towards their marriage - mistakenly believing that he'll impress his wife this way.
When Alfie (Shane Richie) takes things too far by completely rejecting romantic attention from Kat, she heads over to the R&R where she catches up with Mark (former Bill star Chris Simmons) again.
Mark quickly continues his attempts to flirt with Kat and points out that Alfie didn't look at her once when they were at The Vic earlier. Will Kat be wooed by Mark or will she stay faithful to Alfie?
