If that contract requires her participation in filming one of the existing shows, then it would seemingly follow that Deavan would be expected to film again, or else have her contract terminated.
She may not be fired yet, but depending on what this level of attachment is and what’s contingent on it, that eventuality could still happen.
The confusing part is that if Deavan Clegg is still “attached” to Sharp Entertainment as she said above, then one would imagine it would be because she still has an active contract specifically with 90 Day Fiancé, unless there’s another project in the works that nobody knows about.
