Bay and Tank are about to get themselves into a heated discussion on Switched at Birth after Bay finds out who her ex had been living with.

Tank Gets An Unexpected Surprise

On Monday, Entertainment Weekly posted a clip of what happens after Toby lays out his ground rules for Tank as his roommate. When Toby gets a phone call, there's a knock at the door. Tank answers and it happens to be Bay holding a dish and looking shocked to see her ex-boyfriend opening the door.

When she asks Tank what he's doing there, he gives an honest response: "I live here now."

Naturally, Bay isn't sure how to respond to that so Tank explains that Toby needed a roommate.

"Would've been nice for someone to run it by me," Bay haughtily says. But Tank has no sympathy for how she feels. In fact, he throws all her mistakes in her face by teling her how she cheated on him, lied to him and dumped him.

"So I lost all my friends and I became a pariah at school, and that is why I'm living on your brother's couch," Tank angrily adds.

Bay looks like she's holding something back, but gives Tank the benefit of the doubt. He then takes the dish from her, then slams the door in her face.

This could lead to some more heat with questions on what will happen next between Bay and Tank. It's doubtful that their relationship will end anytime soon since he is after all her brother's roommmate.
