The duo even had sex, but by the next morning, Frank had abandoned her.

Shes crushed and devastated and feeling really betrayed, executive producer Pete Nowalk tells EW.

We will obviously see them interact again and its going to be messy.

It certainly comes to a crescendo in Coalport.

Theres so much information on all of that stuff with Frank.

The death of Bonnies father, though a relief, is still a huge loss to her.

Moving forward, theres definitely going to be a shift in how she views him.

Its a pretty devastating move on his part.

However, Nowalk teases that Bonnie and Franks tryst might not be a new thing.

Yes, they sleep together, but I dont know if that was the first time.

Its certainly a massive betrayal.
