It's interesting to see the background graffiti with the "Joker laugh and smile". It really seems to be spreading…
Also why not shoot Freeze in the head? If his body suit takes a shotgun hit and he's fine aim for the exposed part.

I thought Rip was going to do a ghost of Christmas future and show the kid what he causes in the future along with his death, but that didn't happen.

It had some interesting set pieces at least like seeing Jerome's after effects in Gotham. Plus you have some Penguin/Nigma interaction next week it a plus. Not sure how I feel about Nigma's progression into the Riddler though. Seems kinda forced when he's really just overthinking what others are doing.
