A lot was happening on Gotham tonight, not the least of which was a fair amount of fanservice revolving around The Red Hood, The Joker and more.

Oh, and some movement on at least one season-long arc.

So what did we see? What did we miss? Read on...!

The Red Hood

As we discussed earlier tonight, the identity of the Red Hood comes with a lot of baggage but arguably the most significant version -- and the one played with here -- is that the Red Hood Gang is a group of criminals who commit their crimes while taking direction from a central figure in a red hood.

In the comics this figure, who seems to be the leader, is in fact the low man on the totem pole, often a complete outsider.

The idea is to throw the cops off, by making them believe the most expendable one is actually the most important. For all intents and purposes, the red hood is a target.

Joker?

And, yeah, we get the red hood here cracking wise and playing to the crowd. Quiet a joker, isn't he?

Throwing the cash into the air and creating a scene when the crowd goes to snatch it is reminiscent of The Joker's behavior during the parade in the climax of 1989's Batman, too.

Robin Hood

Yeah, Robin Hood was indeed part of what inspired the character of Robin.

Clock King

It sure sounds like that guy with the watch has some storytelling DNA in common with The Clock King, a DC Comics villain who meticulously plans his crimes to the second and who has appeared on The Flash and Arrow.

Reggie

While not a DC Comics character, Reginald Payne was an illustrator of the Thomas the Tank Engine stories.

Ross Potter adds, "He could be based on the World War II wireless operator from no.50 and no.61 sqaudron. I know it may be a bit of a stretch but being based on a British ww2 soldier seemed more likely to me than the Thomas the Tank Engine thing. He did many paintings of planes in distress after the war and I think is still alive."

Wine

Kyle Sheppard said ... (original post)

Don't forget that the wine that bruce brought up was from 1966. The same year the Adam West and Burt Ward started their crime fighting days on TV.

The Dollmaker returns

Dr. Dulmacher is the one who's been farming organs in the place where Fish Mooney is being kept. That would be The Dollmaker, who was a key part of the story early in the season (he was the one who was trying to kidnap the homeless children).

Ivy's wardrobe

That green number with the leaf print is a choice for her, for sure.

Femme fatale coaching

Barbara tried to help Selina figure out how to use her looks as a weapon. Selina wasn't having any of that just now, but it isn't something she's entirely above.

Enemies

"Perhaps it's not our friends but our enemies that define us," Oswald says of Fish at one point. That's quite a thing for The Penguin to say.

Coombs

Jarrod Jones points out in the comments that guest star Jeffrey Combs provided the voice to the Scarecrow in the fourth season of Batman: The Animated Series.
