Season 16, Episode 11 - "A Plague of Doyles"
Denise resurfaces and drops a bombshell on sister Roz – she is moving to Seattle to establish her new pet makeover business. Roz struggles to be a supportive sister, secretly horrified that Denise will be around a lot of the time; also concerned that her business won’t get off the ground. Not wanting to make Denise feel inadequate, Roz starts giving her “anonymous donations”, from a pet-lover. When Denise decides she wants to meet the generous person, Roz must come up with a lie quick, and ends up asking an accountant from the station to act the part. Unfortunately, accountant Jill’s acting skills prove to be a little less than she claimed, and Roz’s charade is found out almost instantly. Roz apologises for not giving Denise the support she needs, and offers her a job at the station until she gets back on her feet. Denise reluctantly accepts, giving Roz the usual excuses to make herself feel superior. Meanwhile, paranoid Noel is plagued with dark fantasies of the “wicked Doyle sisters” taking advantage of him.
