Things are starting to look tense in the next episode of "The Fosters" season 3.

Freeform released the teaser for episode 19, titled "The Show," featuring the rock musical project spearheaded by Brandon (David Lambert). But as the rock musical progresses, the members of the Adams-Foster family will face different trials that could shake them to their core.

Based on the trailer for the upcoming episode, the chemistry between Mariana (Cierra Ramirez) and her former boyfriend Mat (Jordan Rodrigues) will be seen while they portray their roles in Brandon's version of "Romeo and Juliet." Despite their breakup and Mariana's new relationship with Nick (Louis Hunter), the trailer shows that the ex-couple will kiss in the upcoming episode.

However, it seems like the kiss will not go unnoticed, since Nick will be informed of Mariana and Mat's kiss. Will he break up with her because of her infidelity?

Meanwhile, Brandon will also face a love problem of his own after he and Callie (Maia Mitchell) had to end their romance when she became his legally adopted sister.

In the trailer, Brandon will tell Mariana that he had sex with someone, and he regretted it. But Callie happens to be in the adjoining toilet and hears everything that he said. Will this further tear them apart?

The trailer ends with the police arresting someone. Is Mariana involved in this?

The official synopsis for the episode reads:

"As they perform the parts of Romeo and Juliet on the show's big opening night, Mat and Mariana are forced to face the depth of their feelings for each other. The musical performance sparks heightened emotion for members of the Adams Foster family, causing them to reflect on recent events. Meanwhile, a domestic violence call leads Stef to a tragic discovery."

"The Fosters" season 3 episode 19 airs Monday, March 21, on Freeform.
