She's definitely in trouble.

"Oh, fuck."

Kate was heading straight to kill Joe with Nadia's gun after making sure everyone else had left and taking responsibility herself, but when she got downstairs, to her surprise, Joe was already outside.

"Joe, no!"

Joe struggled with Kate, managing to make her shoot herself in the side, leaving her completely exposed and hitting her on the head with the hammer to try to eliminate her... Only Maddie arrived and made him move away from her to try to get him to let go.

Despite being shot and dazed, Kate had enough time to get up, going to hug you and hitting you simply for being there despite her saying she would handle it herself.

"Son of a bitch, I told you I'd take care of it."

That's what she told you after leaving Joe injured on the ground while the whole place was burning on the first floor.
