Absolutely OBSESSED with the way they all know that Reid is literally the best option when it comes to....well, reading stuff, but even so Emily and Morgan still hesitate to give him the guy's journals cause they know that whatever messed up shit he did to those women would be imprinted at his brain forever.
Also the initial reaction to him not getting what Em and Derek were implying- oh you know they only give him the sadist-journals on rare occasions.
And Rossi's response aghaghag "oh yeah he is ok, that is our lil special guy for you" the only found family ever.
Look at Emily's body language here, she so not want her adopted baby brother that tends to touch dead bodies for a living to the unsub's disturbed fanfiction.
the lil, awkward "you can do it champ!" gestures omg I love them, sir those are my emotional support siblings.
