Callie (Maia Mitchell) will turn to Aaron (Elliot Fletcher) as her legal battles compound in "The Fosters" season 4. While Aaron may not have the capacity to get Callie out of the juvenile facility, someone may resurface to help her in her ordeal: her biological father. 

The upcoming episode 13 of "The Fosters" will cast the spotlight on Callie as it will follow her struggles in the juvenile hall. Although she tries to put up her best behavior while inside the facility, she ends up in another trouble after refusing a guard's proposition.

Based on the teaser for the upcoming episode, the guard is seen breaking a glass window of the juvenile facility. Then, a lady guard is seen pushing her against the fence. While it is unclear what the guard's proposition mentioned in the synopsis is, it is suspected that he may be asking for sexual favors from Callie.

While it's true that Stef (Teri Polo) and Lena (Sherri Saum) will do the best they can to help Callie get out of the juvenile facility, they are tied to their responsibility to Jesus (Noah Centineo) in the hospital. Because of this, Callie will turn to Aaron and will develop a closer relationship with him.

"You definitely see her leaning towards Aaron, just because he has been so involved in the case. He's really the one that she's gone to with all the information. He's kind of been her sidekick in all of this. You see her relying and leaning on him. That can be really frustrating for AJ (Tom Williamson), her boyfriend, who is already quite threatened by Aaron for quite good reason," said Mitchell in an interview with TV Guide recently.

However, Callie may not only find comfort in Aaron as the upcoming episode 13 of "The Fosters" is also bringing her biological father, Robert (guest star Kerr Smith), who will confront her daughter's foster parents for not informing him about what happened to his daughter.

As Callie's dad is rich, some can't help but suspect that he may bail him out of the facility just before she gets molested there.

"The Fosters" season 4 airs on Tuesday nights at 8 p.m. ET on Freeform.
