Ashleigh probably did get a warning and she probably apologised and she probably apologised to Christopher but we are not shown this.
We are shown Helen's warning to garner sympathy for her as she 'realises the error of her ways'.
I'm sure none of them are saints but I don't think you could imagine Ashleigh actually carrying out her threat. How many times I your life has a friend pissed you off and maybe you've said something like that?
I'm not a fan of any one housemate but I have a feeling that Helen would lash out physically only she is very aware of the cameras.
So if this is a restrained Helen I'd hate to see her without self control.
Any other year, any other housemate, she'd have been long gone.
