There is a lot of negative energy and emotions after Georgina's eviction that will need to be cleared. Eventually the HM's will want to clean house of it and may start to go after other potential drains/sources such like Charlie...
Everyone in that house has been giving Charlie a pass for all the **** she talks about Jason when she is a major source of problems. It doesn't even matter whether it is true or not, the problem is she can't just let it go.
If Jason is smart, he will step off the tracks and not take part, because there eventually will be a trainwreck over it and he doesn't need to be involved anymore than he already is.
My prediction
