I just think maybe it will be Rutina, as she hasn't been doing many interviews etc at the moment, probably so she doesnt give anything away about what happens to Tara in S5! (I honestly don't think she will be turned into a vamp though!). So doing a convention mid S5 might be a good thing for her!
Oooooh Jessica Tuck is a good idea! I didn't even think of her!
Oh man, if Ryan Kwanten turns up, it would make my year!
