There were a lot of easter eggs and references in the flash latest episode. Let's start!
Cortexin is the drug that makes the animals smart in the Kamandi comics.
This place that grodd went to on earth-2 is the famous gorilla city from the comics.
We get a look at Hawkgirl now that cisco knows she will be on the show next episode.
This sound familiar, well it is a movie. I recommend it to you. Cisco and Hawkgirl watch this movie at the end of the episode.
Barry Allen wheelchair
Barry Allen seems to be using Harrison Wells' wheelchair.
Gorilla warfare is actually a comic book where Flash and Green Lantern go to Gorilla city to defeat Grodd.
