What in heaven is going on with Darnell and Sara?

A playful tussle on the bedroom floor developed into an uneasy awkwardness between the pair.

Sara felt their flirtatious behaviour had gone too far and expressed concerns on how they would be perceived. Moments later she jumped into Stu's bed, ignoring his protests, and asked him what he thought of her relationship with Darnell.

Darnell took his bruised ego and languished on the living room sofa, telling himself he had been a fool on national TV. His desire for a girlfriend is evident. On several occasions he has spoken to his fellow housemates about his need for a special someone in his life.

Rebecca was the object of his desire for a brief moment, but it was short lived and the two became enemies. Darnell's despair grew resulting in him breaking the rules by crossing over the divide into hell. Immediately BB called him into to the Diary Room and ordered him to return to heaven several times before he reluctantly did so.

Can their relationship survive this turbulence or will Darnell turn against her as he did with Rebecca?
