The connection between Brandon and Callie just won't seem to go away on The Fosters.

Connor Is Going To Break 'Even More Grounds' With Jude On 'The Fosters'

On Saturday, a sneak peek of the next episode was released when the family gets ready for a camping trip. When Callie walks outside to put some blankets in the car, she sees Brandon making out with Lou. She realizes that she just walked into a private moment so the couple breaks apart.

Brandon informs Callie that he was just saying good-bye to Lou who said that she's going to miss him while he's away. Callie gives Brandon the impression that he doesn't have anything to explain since he has every right to smooch his girlfriend. But under the circumstances of the 'Brallie' history, things are bound to be complicated.

'The Fosters' Christmas Special Chatter

Brandon and Callie try to keep up with small talk on how they're going to take two cars on the trip since Mariana has a lot of stuff. Brandon then offers to help Callie, but she's got it taken care of.

When she walks to the car, Lou notices that Brandon is "bright red." He tries to deny it, but there's no hiding a blushed face. He informs that it's just because he's not a "PDA guy," which Lou seems to believe. But audiences are aware that his awkward moment has nothing to do with how he likes to do PDA- he probably just didn't want Callie to be the one to witness it.

The scene can be watched below.

The Fosters airs on Mondays at 8 p.m. ET on ABC Family.
