Honestly not much to say about this episode. The play was fun, mostly a summary of what we already knew though. No Lois episode yet but I'm sure it's coming.
Although, holy shit, Frank! I bet Ivy is gonna grow another Frank some time. And also, serial killer Brainiac was something I didn't see coming. What an interesting take on this guy.
Edit: and regarding the play, for Clayface and Bane's sakes, I'm glad the audience seemed to really love it. Kind of a rare win for them. Although actually Bane is winning already with his family.
