None...
Cristian is trying too hard to stand out/impress the audience, as far as I'm concerned he comes out as an attention seeker.
And Sarah making that lame excuse that "I wouldn't have said I'm turned on by fit muscly guys" - no really, like money seems to be a legit answer. controversial statement made to stand out in the auditions, and now she's victimizing herself...

I think Cristian was totally in the wrong tonight. IIRC, all Sarah was saying was that she prefers guys who have a bit of cash, and because of his own poor financial circumstances (he later mentioned not being able to afford going out with his GF) Cristian took it personally and started getting funny with her. That's his hang-up, not hers.

He later implied during their "clear the air" discussion that she was making a big deal out of it - when he was the one who started the argument! Bloody plank.

Sarah!Cristian caused an issue and denied that there was one.

I think he blew it all out of proportion.

So far I think Cristian is a better Housemate, but Sarah was in the right in the argument.

I prefer Sarah, the other one isn't even popular or entertaining enough to have a nickname.
