Austin's a little sharper than most in there, and is clearly very irritated by Chloe. I think he's been in the country long enough to think (rightly or wrongly) that Chloe's accent is fake. People like Janice just love her on principle because she's probably one of those US royalists who thinks Chloe's related to the Queen or something (joke, before anyone says anything

)
I've seen Austin mock her over that accent a few times, and you could tell he was boiling up to having a huge row with her at some point, so no surprises here! And alcohol again! Isn't it depressing how simple humans are really? We'll fight over love, territory and DRUGS! I think almost every major fight in that house has revolved around distribution of alcohol (and then later, consumption of alcohol

)
Of course, Stevi can't really be arsed to defend Chloe (his fiancé in case you didn't know), most of the time, I think partially because she embarrasses him too and partially because he doesn't believe she's genuine either, and finally because it's almost certain their relationship is really just a tool they're both utilising for fame and lols
