Ashley is like Shauna from Yellowjackets
They start out sympathetic, then quickly become less sympathetic. And then over time, the dawning realization that they’re deeply unhinged. And then the final reveal that they’re the actual bad guy.
For the record, I think Lindsay was the most sympathetic character. She would have been fine with Josh quitting his job and selling the house. She just wanted to be happy again.
And I feel bad for Eunice, but only to a point. She knew exactly who she was working for.
