Frank (William H. Macy) wants to marry crazy Monica (Chloe Webb) again in the upcoming episode of "Shameless." Will their children approve?

In the episode titled "Happily Ever After," the synopsis (as per CarterMatt) reveals that Frank will gather the kids to tell them something important. After spending some time together and robbing people, the two have decided they are ready to tie the knot. Since Frank is still married to Sheila (Joan Cusack), a legal wedding between him and Monica seems impossible. He does not care though, even after remembering everything he had been through when Monica decided to leave him and the kids.

Fiona (Emmy Rossum) thinks the whole thing is stupid. For her, her parents should stay divorced forever. In the promo, she angrily tells Frank that marriage with her mother is out of the question, but he does not listen. Later on, Monica is revealed to be wearing a wedding dress. Instead of celebrating, she and Frank cap the day by punching each other. Will they end up "divorced" again?

Meanwhile, Fiona is eager to start a new business. She already decided to sell the laundromat last episode.

Elsewhere, Ian (Cameron Monaghan) will make a terrible decision by running away with Mickey (Noel Fisher). Last episode, Mickey escaped from prison and met with Ian. He told him he would leave the country via the Mexican border. Mickey wanted Ian to decide whether he would come with him or not. The Gallagher kid ultimately chose to run away with him. He chose to leave Trevor (Elliot Fletcher), even after Fiona warned him about his ex. It looks like he will soon regret his decision, though. In the clip, Mickey must have robbed a store. The angry owner follows him, raining bullets at their getaway car.

"Shameless" season 7 airs Sundays at 9 p.m. EST on Showtime.
