Tensions are running high on this week's episode of The Fosters -- and we wouldn't have it any other way!

In tonight's all-new hour, AJ -- yes, the same AJ who broke Callie's trust and got her fired from the drop-in center -- is coming to stay at the Fosters' house while Mike works on getting his fostering license.

But if you think this is going to be the new one big happy Fosters family, then we clearly have not been watching the same show.

"So the real kid gets his own room?" AJ asks with a severe amount of snark in his voice while rummaging through Brandon's things. But Callie doesn’t have time for AJ's judgmental behavior -- she's got some confronting to do.

"Look this, 'Yes Ma'am' act? I know you don’t appreciate being here and you just wanted to get out of Juvie so that you could run again," she said.

"I got fired from the drop-in center because of you," Callie added icily. "If my moms knew about that, you wouldn't be here."

Better watch out, AJ -- you never want to have Callie on your bad side!
