"The Fosters" Season 3 Episode 12 is turning out to be upsetting for Brandon (David Lambert) as someone had discovered that he shared a bed with Callie (Maia Mitchell).

If the secret explodes, feelings will be hurt and they will become the talk of the town now that they are officially siblings -- and what happened between them is officially incest.

Callie is also being distracted as she gears up to take her Fost & Found website to the next level.

In the previous episode, Callie receives an offer for a significant financial investment in the project. The news opens many opportunities but the young girl has her reservations.

"I have this huge secret," she tells Brandon. "How am I supposed to let people think that I am some kind of role model?"

"I think you're just afraid," Brandon, who is also heavily affected by the situation, replies, "You're holding me back, too."

"The Fosters" Season 3 premiered Monday with a heartbreaking episode which answered many cliffhangers left when the series paused this summer, reports International Business Times.

A.J. (Todd Williamson) decided to leave the town quickly with his brother. A second opinion confirmed that Stef's (Teri Polo) did exhibit signs of cancer.

"The Fosters" Season 3 airs Mondays, at 8 p.m. ET on Freeform.
