I've liked Ed Nygma from the start and he was amazing in this chapter. The clock riddle, thecrazy laugh when Gordon found out and how he shocked him right after made an amazing Riddler scene. I was ready to call that moment the highlight of the episode when out of the blue comes Penguin pulling an old fashioned psychopath move "You say they taste the same, but I find Shasha more tender" and then off you go you gold digging witch. Of course I also love that Gordon cleaned his name but I am so angry that he didn't called Lee, like, dude, come on, don't do her wrong like that. Bruce also was cold to Selina, but, well, he has a better reason to do so. Oh, and of course Barbara comes back, I've never really liked her, but, I'm still curious to see what Jim will do now. Overall amazing episode.
