Jesus (Noah Centineo) will become even more unbearable in the upcoming episode 15 of "The Fosters" season 4 as he accuses his brother, Brandon (David Lambert), having a relationship with his girlfriend, Emma (Amanda Leighton).

Although Jesus is now recuperating in their home following a life-threatening accident some episodes ago, his temper is becoming more difficult to handle. Based on the synopsis for the upcoming season 4 episode 15 of the Freeform drama, he will even accuse Brandon and Emma of having an affair.

As seen on the promo for this week's episode, Jesus is seen confronting Brandon and Emma. As Brandon tells him to calm down, he goes berserk and smashes the glass of water on the table onto the floor. While it remains unknown what will happen after the said scene, it is suspected that Jesus and Brandon will eventually get into a physical fight.

To recall, Jesus got knocked down in "The Fosters" season 4 summer finale after attacking Mick, thinking that Mariana (Cierra Ramirez) was in trouble. It resulted in a brain damage that required him to be in an induced comatose when the Freeform drama returned for its season 4 winter premiere (episode 11) last month.

While he survived his ordeal, Jesus has even become more temperamental, and his mood swings are taking a toll on the people around him. With Emma telling Brandon that she is pregnant with Jesus' child in last week's episode 14 and swearing him to secrecy, it is but understandable why the two will have some private conversations and moments. Unfortunately, this will not sit well with Jesus, much more that he had dreamed about his brother and girlfriend cheating on him. 

Meanwhile, apart from the Jesus-Emma-Brandon drama, the upcoming episode 15 of "The Fosters" will also feature Jude (Hayden Byerly) using a dating app for adults in order to learn more about LGBT sex after he finds out that the topic is not included in the sex education subject.

"The Fosters" season 4 episode 15 comes with the title "Sex Ed" and airs tomorrow at 8 p.m. over Freeform.
