Mavis

Mavis is a fixture of the Briggs household from the very first scene, moving through the family's daily scrapes and squabbles with the unbothered air of someone who has seen it all before. She keeps things running, dispenses opinions freely, and treats Jonny's schemes with a mix of exasperation and affection.

Debbie Norris plays her with a dry, unhurried confidence that grounds the sitcom's chaos in something recognisably domestic. The part could easily be background noise, but the performance finds comic timing in small reactions — a look, a sigh, a flat retort — that make Mavis feel like the household's quiet ballast.
