Marnie

Marnie is one of the many locals who populate the town of Schitt's Creek, part of the ordinary fabric of the community the Rose family finds themselves stranded in. She goes about her small-town business with the same unbothered familiarity as her neighbors, unfazed by the newcomers' big-city airs.

The show's genius has always been its supporting cast of townsfolk, whose plain-spoken normalcy throws the Roses' pretensions into comic relief. A character like Marnie works because she doesn't need to do much — her steady, unimpressed presence is the joke, and the quiet confidence of the performance sells it.
