Bay's (Vanessa Marano) downward spiral continues after her bittersweet trip to Mexico. 

In the next episode of "Switched at Birth" season 4 titled "Borrowing Your Enemy's Arrows," Bay will have a chance encounter with Tank (Max Adler) inside the restaurant where he is currently working. But based on the trailer, the awkward run-in between the two will affect not only Bay. Tank seems to be deeply affected with the rape allegations that Bay threw at him during the first half of the season. 

In the promo video for "Switched at Birth" season 4 episode 16, Bay runs after Tank and begs him to talk to her. Tank simply asks her one question: "Do you know what it's like to realize that the rest of your life, someone searches your name and the word rape comes up next to it?" 

But why does Bay want to talk to Tank after everything that happened between them in the first place? 

Meanwhile, Daphne (Katie LeClerc) will encounter problems of her own when she and her current boyfriend Mingo (Adam Hagenbuch) decide to introduce their parents to one another. The trailer shows Mingo and Daphne's dad John (D.W. Moffett) in the middle of an ugly bantering, leading Daphne to shout "Stop!" 

According to the official synopsis, John realizes that Mingo's father is the reason why his family is having financial problems. It reads:

Daphne and Mingo decide to introduce their parents at the Kennishes' grill night, only to find Mingo's father is the business manager John blames for his current financial problems. Bay has an awkward run in with Tank at the restaurant where he works."

Will Daphne ever make her parents, particularly her dad, like Mingo after the events during the grill night?

"Switched at Birth" season 4 episode 16 airs on Monday, Sept. 28, on ABC Family.
