The upcoming finale episode of "Switched at Birth" season 4 will see the Kennish patriarch and matriarch fighting over their recent money troubles.
Throughout the past couple of years, John (D.W. Moffett) and Katherine (Lea Thompson) have shown how strong they are as a couple.
With everything that has happened to their family, the Kennishes have stuck with each other, and have supported each other no matter what.
However, in "And Always Searching for Beauty," the couple will be seen fighting after John walks out of a huge deal negotiation.
Since the couple is badly in need of money, Katherine would be pissed at John for letting another offer slide.
Meanwhile, the couple will also confront Regina (Constance Marie) about Eric's (Terrell Tilford) secret, according to Cartermatt.
In the previous episodes, it was revealed that Eric kidnapped his son to make sure that he will be away from his mother.
After learning this, Regina agreed to keep Eric's revelation a secret.
In other news, Daphne (Katie Leclerc) and Mingo (Adam Hagenbuch) will be faced with their own relationship problems.
Daphne will receive an offer for an internship abroad. If she agrees to accept it, she will be closer to Quinn, the guy who helped her in Mexico.
Mingo will obviously not be okay with Daphne living closer to Quinn because he knows about their kiss.
Daphne will be torn between her job and her boyfriend, and fans believe that Mingo has to be open-minded if he wants Daphne to stay with him.
"Switched at Birth" season 4 will air its finale episode on Monday at 8 p.m. ET on ABC Family.
