LJ may seem happy but is secretly terrified that one day he'll forgotten again, but this time by the people he calls friends (That aren't the kids)

(Oc ones next)
Whenever Sally is upset, Ada will possess a doll like she does to scare people, but instead she will play games with Sally while possessing a doll to cheer her up.
Callie may seem calm and confident, she can walk around at night because the moon and houses give off light, but put her somewhere with no light whatsoever and she will be terrified.
Reginald is very over protective of his sister, for example someone so much as looks at her the wrong way and Reginald will go into over the top big brother mode, raging at the person and trying to hit them while Ada tries to hold him back.
(Back to other CP's)
Sally probably owns hundreds of dolls.
Jane definitely has a picture of Jeff pinned to a dart board like people do in movies when they hate someone, just so they can imagine the person's face is the target for harp objects.
EJ will eat any other organ if a person has a problem with their kidney's, either way the person will die though.
BEN ha played a video game with a lot of female characters in it t some point and secretly loves one of the characters even though they aren't real.
Toby probably loves animals. (Sorry I randomly pictured Toby petting a random cat that he saw while out killing and it has now become my new head canon)
