If the girls are choosing which boy gets dumped then I don't see why they won't choose Billy. Paige and Indiyah will want Dami to stay and will influence the others (not that anyone is really enamoured by Billy imo).
Likewise, if the boys are choosing the girl to go, I reckon they'll pick Danica. In the First Look they were making a comment about her already having lots of chances.
I really, really want one of the new boys to flirt with Gemma and set Luca off again. For some reason G doesn't seem to have opened her eyes yet to what he's like, and the message needs to be reinforced. Either that or she's very well aware and is just playing the game until the end to avoid friction.
