I liked last episode quite a bit. Miss Martian is like an exchange student trying to be nice with everyone and she does quite well.
Superboy having dark mood is quite odd and very different from the "Reign of Supermen" storyline in which he appeared for the first time. Most likely that one of the members of "The Light" might be his "other daddy" than Superman. Actually, Supes acted like a jerk role model with him in the premier episode.
Speedy role is intriguing me. He's been shown very resentful with no extraordinary reason and I'm quite amazed that Green Arrow took it so lightly. I wonder if the "Snowbirds Don't Fly" storyline is going to be adapted or hinted in any way or they will go with a lower or similar tone as Red Hood Jason Todd.
