Nina
Nina was a friend of Julia's. At some unknown period of time, she befriended Andy, and later; Leyley.
Playing Hide-and-Seek with the Graves Siblings'
In one of Ashley's memories, she was playing hide-and-seek with her brother and Nina. With a look of mischief, Leyley picked Nina as the hider with two seekers being the Graves siblings. Nina, with a look of confusion, declared this as unfair and demanded another hider. Leyley accepted her request, but made all of the players hiders and hosted the best hiding spot of all. However, Leyley had other ideas as she swayed Nina to a large treasure chest big enough for Nina to curl into a ball, to which Leyley commanded Nina to. After she locked the chest box, Leyley announced that Nina had to stay inside that box which brought dismay for Nina. Nina was in more disbelief when Andy didn't help out when Leyley was about to kill her.
Cover-up of Nina's Death
After a certain amount of time passed, Leyley and Andy opened the treasure chest. Nina died due to lack of oxygen. Andy becomes aghast as he peered over her lifeless body and yells at Leyley as he was worried that he and Leyley will get caught and go to prison and couldn't take care of her. Leyley calmed Andy down and assured him that won't happen to them as they would carry the treasure chest to a dug-up hole and bury Nina in that hole.
