Not at all, he was 100% in the right during every point of the argument.
Should she have stolen the cans? No, if she wanted take the alcohol for them, why didn't she ask instead of just running off with them in a sneaky way?
Austin was correct in saying that she's been around alcohol every day in the house and she hasn't seemed to have an issue with it before. Plus, Big Brother wouldn't let a real alcoholic into the house to begin with, so she's lying.
She should have come outside to toast to Austin's brother with everyone else, why is she letting Janice tell her what to do as if she's her mother or something? Or at least spoken to Austin about it, but seemingly she didn't which looked extremely disrespectful.
She then continued to cry and play the victim. A typical day in the life of Chloe.
