Tonight's episode of The Flash was fast and crowded.
And while I didn't get a good enough look at any of the Earth-2 metas to really make a judgment call on just who they might have been, it was still easy enough to spot a few little Easter eggs along the way.
So...what did we see? What did we miss?
Read on, and comment below.
When Iris referred to the "metapocalypse" as "the blackest of nights," it certainly evoked a familiar DC Universe turn of phrase.
"In brightest day, in blackest night, no evil shall escape my sight," says Green Lantern's oath. And Blackest Night in and of itself was the name of a storyline that involved reanimated versions of dead superheroes, villains, friends and foes rising to attack their former loved ones.
In the DC Animated Unvierse, Donna Nance is Black Siren, a reimagining of the Golden Age Black Canary who works with the Justice Guild in the '60s in Seaboard City.
Tonight we saw Tina McGee flirting with Henry Allen.
McGee, played by Amanda Pays, first appeared on TV in 1990's The Flash, in which John Wesley Shipp played The Flash and Pays played McGee, his on-again, off-again love interest.
We've seen McGee a bunch before now, but this is the first time she's shared the screen with Henry.
DIMENSIONAL TUNING FORK
The Cosmic Tuning Forks that were constructed by The Monitor in Crisis on Infinite Earths were used in a very similar fashion to what The Flash described this week. They managed to disrupt the vibrations of the shadow demons who served as the foot soldiers for the army of the Anti-Monitor.
The body of the Anti-Monitor was later used to construct a similar device in Infinite Crisis, seen above.
