This makes sooo much more sense. Irene is such a cool grandma. It’s a good thing Casey has her. Makes me wonder why she let Casey be abused all those years though.
So, does Pete know everything that happened to Casey? Did Irene tell him?
But yay, Pete to the rescue!

Glad it was all sorted out ^^ If you look back on Chapter 8, which is a way far back, Pete mentions to the guys that Casey herself told him some stuff that he wanted to help her through. It was the chapter after Pete came to her apartment when she got back from seeing her grandmother.
