"The Flash" episode "Gorilla Warfare" was not exactly one of the more action-packed episodes that the series has had to offer, although it may be wise to hold on to that episode for future reference.

Grodd, that telepathic ape who is deemed perhaps one of the more dangerous adversaries of the Flash (Grant Gustin), returned out of nowhere and, apparently, his sighting was meant to lay the groundwork for how he would make life harder for the Flash and his team.

Caitlyn Snow (Danielle Panabaker) had sort of a push in that episode, rekindling the ties he has with Grodd. Could this have any bearing with that twist which would turn her into Killer Frost? If you failed to catch it, alleged photos of her as Killer Frost were reported over at Cinema Blend.

Moving on, it seems that the episode provided a glimpse of Hawkgirl/Kendra Saunders (Ciara Renee) when she was "vibed" by Cisco Ramon (Carlos Valdes). This will most likely be the start of feelers leading up to that much awaited crossover of "The Arrow" and "The Flash" this coming December.

So what is Harrison Wells (Tom Cavanagh) really about? Is he good or bad? He does bring a different kind of character with his touchy persona, but one has to wonder if he will ever become the Reverse Flash once more. He did put on the suit sans the power and such really caused quite a stir within the group.

And the finale gave viewers a glimpse of Grodd's new home, Gorilla City. People who are familiar with it (either in the comics or through some animated films) are pretty aware that this could eventually cause trouble for the Flash and Central City. The only question now is when will Grodd figure it out and eventually he will.
