I was quite satisfied with the end of the first season, ending with Artemis and Wally which was long overdue, but I felt inherently bad for Roy! At first he was a huge jerk, but I felt so bad when he realized he had no idea who he was at all.
Robin and Connor did an awesome job teaming up against their mentors and Klarion bothers me SO much. He was annoying in The New Batman Adventures, and he sucks in this show too! But this episode didn't suck at all!
