Calum... which I'm surprised by. For some reason I never expected to like him but I think he comes across very well. I just wish he got more airtime. I like Alicia too.
It's purely by process of elimination though since most of the others I'm either neutral towards (Kavana, Alex, Keith, Patsy), are disappointing me (Michelle, Katie H) or I just plain dislike (Cami Li, Nadia, Perez). Too early to tell with Katie P.
