Reminiscent of Parker Posey in Schitt's Creek

Now that you mention it, I agree with you. On 12 Monkeys she has a sense of humor that is great: despite the more serious nature of the show.

Makes sense since she's working with a bunch of Christopher Guest's favorites. They would need a Parker Posey type. Although Guest isn't involved in Schitt's Creek it definitely has that feel.

Not to mention she physically resembles Posey.
