That the marriage is fake.

However - she thinks they [Mario & Steph] are actors, rather than task HMs.

At first she suspected it was a task cos they were both first in, then she said 'BB have chose bad actors'.

Apparently she plans on crashing the wedding and objecting.
But they will still (presumably) pass unless she suspects Lisa is involved.

She's already said the certificate is fake.
She's said the photo of M + S is fake.
And she's said they act weirdly around each other.
And that Steph is sleeping in a separate bed from Mario tonight, despite it being two nights before the wedding night, rather than the traditional one.

Thoughts?
I personally think Steph hasn't tried hard enough, but they still might pass cos no one has suspected Lisa. It only takes one slip up though.
