Brigitte is no fool, she is also a veteran of several reality shows in the US - this is how she makes her money nowadays. She must have known that there is no such thing a reality show without a twist or sting in the tail - she may not have known it was going to affect her so directly but she must have been aware of the possibility of something totally unexpected happening.

She still might not "have imagined how low Endamol would stoop."

Also, if BB does something obnoxiously nasty, that HMs "must know" that BB can be obnoxiously nasty does not stop it from being obnoxiously nasty.

An effective, but toxic catalyst, I'd say. So long as she is on screen or heard, the show is poisoned.

I do not want to hear this woman's weird ideas, her complete cluelessness about BB, or pretended complete cluelessness, or FMs enthusiastically quoting whenever she says something that seems nasty about John or Brigitte.

Also, she frightens my cat.
