"The Fosters" season 3, episode 18 will see Brandon and Callie breaking each other's hearts again.
In "Rehearsal," Mariana's secret will also be revealed, and she will fear that Nick might decide to leave her when he finds out that she cheated on Mat in the past.
Freeform recently released the synopsis for episode 18 which read, "During a rehearsal for Brandon and Mat's 'Romeo and Juliet' musica, Zoe tells Nick that Mariana cheated on Mat when they dated, causing Mariana to fear that Nick will end their relationship."
The episode will also see Callie acting as a character witness for her friend Daphne. The latter has been desperately trying to get her daughter back.
Also, Jesus and Mariana will attempt to help their biological father who they just met recently.
In the previous episode, Jesus and Mariana's dad went to their house to give them a gift for their birthday.
Meanwhile, Freeform just dropped the teaser for "The Fosters" season 3, episode 18.
The clip showed Brandon talking to Mariana about having sex with a woman that he shouldn't have slept with.
What Brandon didn't realize was Callie was just standing in the bathroom, and could hear him.
Although it's still unclear whether or not Brandon was referring to Callie in his statement, it was previously established that the two could never have sex because they are now siblings.
"Mat had a good reason to break up with Mariana. She cheated on him," Zoe told Nick.
The next scene showed Mariana and Brandon talking to each other.
"I had sex with someone, and it was wrong, and I regret it," Brandon said in an attempt to console his sister.
Another scene showed Mariana talking to her biological father. However, just out of nowhere, police officials arrived at their house.
"Hands where I can see them," one of the officials said.
Mariana and Jesus' father was previously listed as a sex offender for sleeping with their biological mom who was still a minor back then.
It is unclear whether or not the police's visit has something to do with this.
"The Fosters" season 3, episode 18 airs Mondays on Freeform.
