I'd like him to stay.
I always try to consider what a person might have going on in their personal life, but I don't like to use it as an excuse for bad behavior. It may be a reason but never an excuse. I think what Austin said to Janis tonight was shocking, he was totally wrong.
However, his "breakdown" in the DR and then re-entry to the house did soften my opinion and I felt it was probably genuine. He went nuts, made a mess of everything, saw his errors, and then it all crashed down around him when he realized how awful he was. So, because of this I give him a bit of slack where I gave Farrah zero. Never once did I get the feeling Farrah gave a shit about anything she did and was so up her own arse that she really didn't have any regret when she hurled abuse at others. It all comes down to believability and I believed Austin - but not her. Not even for a second.
He did make a fool of himself though, and I shudder to think what it will feel like if they play that back when he's evicted.
