The team had just had a long, gruesome case, a child abduction case where the Unsub took children from outside their schools and hurt them beyond recognition. Against Prentiss' wishes, you'd worked the case, the whole team, except Alvez, knew what happened to your daughter seven years ago, when Foyet killed Haley and your little girl.
You and the team are on the jet, finally going home. JJ, Simmons, and Reid are playing cards, Prentiss is working on case reports, Alvez is playing on his phone, and you are writing yet another novel, trying to keep your mind off of your late daughter. Occasionally, the team looks over at you, making sure that you don't break down.
Luke slides into the seat beside Prentiss and opposite you.
"Why is everyone watching over Quinn?"
Luke asks, genuine curiosity in his tone. Prentiss sighs, replying to him.
“That's not my story to tell, Luke, maybe ask her."
