Jack is the 'stop the intense talk *walks away*' twin.
Joe is the bigger twin, the pessimist and the more rude/spiteful twin.
I love Gina she is so kooky and O like Dexter too, I think he gets nominated and a hard time for nothing.
I think Callium is dragging Sam down with him and making him look a prat too.
Charlie is just a vessile, no opinion and craves male attention.
Hazel is a sneaky, twisted individual who has jumped from man to man in the house. In my eyes she hopped on Daley knowing he was in a relationship, she then behaved inappropriately and wound up the situation he was removed from the house for.
Sophie is hilarious, really silly but sweet and no pushover.
