Forgive me for not caring much should Steph and Cam ever get together outside the house, and as I see it there is no chance of that happening anyway. There is little chemistry between them, certainly none that would suggest they could ever be romantically involved, and Cam has already shown his disgust by wiping his mouth after they kissed. They have formed a valuable alliance in the house and hence the reason why they are close. It will never materialise into anything more than friendship.
