The perfect out for the prods
 

If BB tell Helen to say something bad to one of the HM,s and get her in the DR then into the secret room. That would be gold as the HM's will all think she has been warned and evicted. They wont need Armageddon then, Helen will start ww3 when she gets back in.

They could even fix the eviction if they wanted to get rid of a muppet and keep Ashleigh for the fall out when Helen gets back in, but alas this kind of logic is way beyond them and they will probably let Ashleigh go and loose Helen next week, offer Steven and Kimbo a wedding party, let scammer Danielle take her dog in and give Mark and christopher sleep in a sound proof booth with porno movies and no cameras..
