Gurl, don'choo even. *wags finger*
Where she was? She was married to one of the biggest criminals in Harlan County. And then she killed him. He was an abuser, sure, but most abusees don't kill their abuser. Ava did, and I think that says a lot about her character.
She had a relationship with Raylan, sure, but that didn't last very long and she's been hanging around Boyd and Co. ever since.
It is a bit of a stretch to see her slapping hookers around, I'll admit, but season 3 was filled with shoddy writing so I just chalk it up to that and not necessarily as indicative of a flaw on Ava's part.
