I'm not sure either, the behaviour is disturbing though. Yesterday she was firmly telling Curtis and Amy it was because apparantly Danny needed constant reassurance and that was the issue, and today's she's attempted to tell Michael it's the opposite and he made no effort with her, just didn't bother with her. And that rather oddly he's the rude one.
At least the others are calling her out on it and not letting her away with it.
Danny seems to genuinely like her, and seems quite unsure of himself. She's really pretty and clearly intelligent, but you can't be treating people like that. It's not ok.
