"The Fosters" will air episode 5 of season 3 on Monday, 6 July, and as the title -- "Going South" --suggests, somebody is taking a trip down south. Meanwhile, there is also a pregnancy scare; could it be Mariana?

According to the synopsis, Callie (Maia Mitchell) convinces Brandon (David Lambert) to go to Mexico with her, which could have something to do with finding JJ's brother. Although she is heading down south in search of some crucial information, travelling together might mean bringing back "Bralle" in season 3.

Meanwhile, Callie's former boyfriend Wyatt (Alex Saxon) was last seen sleeping with her foster sister Mariana (Cierra Ramirez), after her boyfriend refused to be intimate with her. In the promo for "Going Douth", the mothers find a pregnancy kit in the trash, and wonder which of their children are pregnant.

"What if she is pregnant," Lena (Sherri Saum) asks Stef (Teri polo), as Mariana's visuals are flashed. Could it be that Mariana is pregnant with Wyatt's child?

Find out in season 3 episode 5 "Going South" of "The Fosters" on ABC at 8.00 pm (EST) on Monday, 6 July or stream it live on Hulu or on the ABC website .
