Yeah, it's hard to imagine them so sluttily allowing the situation to continue to escalate. Hazel could have ended the whole thing instantly very easily. She didn't because she was enjoying it very much.

I didn't actually really like the way they were quoting her confidential diary room quotes, what housemates say in private to Big Brother is supposed to remain that way

Here is what Daley thinks of his ejection:

Hazel is no naive colleen from the backwoods she is a savvy business woman who realised as soon as BB called Daley to the diary room that the jig was up! far from running scared to the couch, it was a show of guilt that they had been caught out. Simple damage limitation tactic.
