A look back at the Easter eggs and comic references from last night's episode.

Welcome to Flash Facts, a weekly column dedicated to discussing the various comic book references, Easter Eggs and other cool facts about The Flash, CW's new superhero show. While I'll attempt to be as thorough as possible, I'll definitely miss a reference here and there. If I miss something, feel free to comment or shoot me a Tweet at @TheOuthousers, and I'll gladly add it in and credit you. If you enjoy this column, be sure to check out Arrow Annotations, which discusses similar references over on Arrow.

General Eiling - If you want to read up on General Eiling's history in the comics, check out the Flash Facts for "Plastique".

Dothraki - Mason Bridge tells Iris that the STAR Lab particle accelerator plans make as much sense as Dothraki to him. Dothraki is a fictional language that appears on Game of Thrones.

"Impossible's just another Tuesday for us" - When discussing how impossible it was for Ronnie and Dr. Stein's brain waves to be in sync, Barry mentions that impossible is just another Tuesday for them. That's a nice little nod to fans about the show airing on Tuesday.

The Flash and spines - One of General Eiling's weapons covers Barry in spines attracted to kinetic energy. In the 1980s, the Flash briefly transformed into a "porcupine man" after losing his memory during an experiment. During that storyline, the Speed Force manifested itself as a number of spikes protuding from the Flash's skin, leaving him hungry and disoriented.

"Dude that can turn into poison gas" - Cisco reminds the team that the Mist is still imprisoned in the Pipeline underneath STAR Labs. Cisco also points out that the Flash's battle with the mist occurred in "like week three", which lines up nicely since "Things You Can't Outrun" was the third episode of the season.

Sam from Coast City - Caitlin introduces Ronnie to Iris as her cousin Sam from Coast City. Coast City is the home of Hal Jordan, the Silver Age Green Lantern.

Dr. Stein's torture - Eiling notes that the last time he used a cattle prod, it was on a gorilla. As referenced at the end of the episode, Eiling and Dr. Wells previously experimented on Grodd before the particle accelerator explosion.

Firestorm - After merging with Dr. Stein, Ronnie's eyes turn entirely white, which is a nice little nod to Firestorm's appearance in the comics. Ronnie also remains in complete control of his body with Stein guiding him as a disembodied voice, just like in the comics.

Pittsburgh - Ronnie tells Caitlin that he and Dr. Stein are fleeing to Pittsburgh, where Stein has a colleague that can help study their condition. Both Ronnie and Dr. Stein were from Pittsburgh in the comics.

Midway - Iris catches Caitlin in a lie when Caitlin says that "Sam" is from Midway instead of Coast City. In the comics, Midway City is the home of the Silver Age Hawkman and Hawkwoman, as well as several versions of the Doom Patrol.

Electrical disturbances - This week's end scene nicely ties into last week's end scene in a few different ways. Besides the obvious Grodd connection, General Eiling notices the lights flicker shortly before he's kidnapped by the Reverse-Flash. In the previous episode, two electrical workers note that there has been a number of electrical shortages in the area that Grodd has been hiding. The clear hint there is that the Reverse-Flash has been visiting the Grodd for some unknown purpose.

Grodd - Speaking of Grodd, IMDB credits stunt actor Simon Burnett as playing him this episode. Burnett has appeared on Arrow and The Flash as a stunt actor before, and also did the stunts for Buck the Gorilla in Rise of the Planet of the Apes.

And that's it for Flash Facts until March. Thanks for reading!
