Season 2 of The Flash is back and it did not disappoint. 'Potential Energy' is far from the most optimistic episode of the hit CW series, but it served to further a few tantalizing plot points whilst setting up the rest of the season.
'Potential Energy' devoted a healthy amount of screen time to Wally West (Keiynan Lonsdale) and his estranged father, Joe (Jesse L. Martin), without rushing the uncomfortable family drama.
Moreover, Barry's relationship with Patty was hit hard in 'Potential Energy' and we've seen that Barry is still suffering some severe emotional stress after his confrontation with Zoom... I guess a broken back is pretty heartbreaking!
As I've said, the episode wasn't one of their most memorable, but it was very welcome. The Flash: 'Potential Energy' felt reminiscent of Season 1, with a big bad of the week who was ultimately locked up by team-Flash. Fortunately, amidst this collage of madness there was time to fit in a few references, so let's have a look, shall we?
In The Flash: 'Potential Energy' we learned that the "Crystal Ball' had been recovered from Markovia, a fictional European nation from DC comics.
Moreover, in the Arrow CW series, Dr. Markov was the scientist behind the Markov device used during The Undertaking in The Glades.
In the comic book source material Markov was known as "Geo-Force" and was the prince of Markovia.
Did you catch the reference to Laura Vandervoort? The Vandervoort Diamonds played a role in 'Potential Energy'; interesting considering Smallville's Laura Vandervoort (Kara Danvers/Supergirl) has just been recruited to the Supergirl television series. That's right, Smallville's Supergirl is joining Supergirl as Indigo!
3. The Turtle
The villain of the week in The Flash: 'Potential Energy' was The Turtle, which is a legacy name used by a number of different Flash villains. Generally the villain has the ability to steal the speed from those around him, hence the episode title: 'Potential Energy'.
The Flash has had much more exciting villains of the week, but The Turtle tied in well with the ongoing narrative of the show. In addition to playing off the relationship between Barry and Patty, it seems The Turtle will also play a role in Wells's (Tom Cavanagh) future plans to bring down Zoom... or Barry?
4. Naydel Library
Okay, this is just a small one, but I feel it's worth mentioning. In The Flash: 'Potential Energy' we saw The Turtle operating out of Naydel Library, a place where the collector stores his victims. Interestingly, The Turtle was originally created by Gardner Fox and Martin Naydel; it's a small reference, but a deserving nod to the villain's creator.
5. Keystone City
The Flash: 'Potential Energy' had yet another reference to Keystone City, the comic book home of Wally West, a.k.a. Kid Flash. It has also been established that Eobard Thawne, a.k.a. Reverse Flash, is from central city. Now... what relevance could that have?
6. Reverse Flash!
It's not exactly a reference, but it needed to be acknowledged in the breakdown of The Flash: 'Potential Energy'... Reverse Flash is back! Reverse Flash, a.k.a. Eobard Thawne, was the villain of Season 1 who was ultimately wiped from existence, but of course it's The Flash and anything is possible!
It's difficult to say what role the new Eobard Thawne will play in The Flash. Could Reverse Flash replace Zoom as the overarching threat of The Flash: Season 2? Moreover, will the show's creators take advantage of this opportunity to pitt Zoom against Reverse Flash, and will Harrison Well's somehow steal the villains speed and become DC's Johnny Quick after all?
