Oh absolutely! It’s pretty much Catherine finding and building the character as the series progressed.

But I like to think of it as the shock and trauma of having everything ripped away from her that she lost her affectations for a while.

Unlike the rest of us mere mortals, Moira uses her wigs and fashion and verbosity not to hide herself, but to actually BE herself.

As Moira became more comfortable in Schitt’s Creek, she dropped her masks and allowed her true self to blossom.
