I kind of figured who the arsonist was about half way through the episode, and I like that it wasn't the straight up evil act that was first thought, he was just a kid that had had enough and made a bad decision that he now has to live with for the rest of his life.
Loved the muster stuff
Absolutely loved that we got some Gabby/Stella friendship time. I feel like that was long overdue, and I'm glad they haven't dropped Gabby's issues following the cliffhanger, especially when all we got was a look - I wonder if the aim is to make us think she's getting past it only for it to all come to head later on.
I'm intrigued by Sylvie's friend. I wonder what's going on with her. Hope we're not waiting too long to find out.
