The Flash Cameo in Next Week’s Arrow Episode Revealed?

Arrow The Flash Season Finales

Over the past few years, The CW has built up its shared television universe focused on DC Comics superheroes to include Arrow, The Flash, Legends of Tomorrow, and CBS transplant Supergirl. However, it all started when Arrow debuted in 2012. The CW's flagship DC series then acted as the launchpad for The Flash, introducing Barry Allen (Grant Gustin) in a two-part storyline before the character returned to Central City - where he was hit with a blast from the S.T.A.R. Labs particle accelerator explosion that granted him his metahuman powers.

The following season - year one of The Flash and three of Arrow - The CW featured its very first DC Comics crossover, spanning an episode of each series. Since then, the crossover events have expanded to include Legends of Tomorrow (in fact, last season's crossover launched the second CW spinoff starring characters from both Arrow and The Flash) and more recently Supergirl in this season's 'Invasion!'. Now, Arrow is gearing up for an extremely quick crossover in next week's episode featuring The Flash.

Marc Guggenheim, an executive producer on all four Arrowverse series, previewed the crossover in a recent interview, calling it "the fastest crossover with Flash we’ve ever had." The producer reiterated his statement on Twitter, accompanied with a photo of The Flash slapping a sticky note on a computer in an office setting. Take a look:

It's unclear whether the photo is actually taken from the upcoming episode of Arrow, titled 'Second Chances', or if it's simply a photo of The Flash to illustrate Guggenheim's point about it being the "fastest crossover." The setting resembles the office of CCPD Captain David Singh (Patrick Sabongui), who looks to be featured in the image. As such, it's likely this photo is taken from a previous episode of The Flash, used as an example by Guggenheim of how quickly The Flash will be in and out of the Arrow episode.

'Second Chances', for its part, will also feature the official introducing of potential new Black Canary, Tina Boland (Juliana Harkavy). Team Arrow meets Tina in the extended trailer for 'Second Chances', but the woman - who seems to be a metahuman with an ability similar to the Canary Cry - is less than enthusiastic by the proposition of joining Oliver's team as Black Canary. Since Tina appears to be a metahuman, it seems likely Oliver will either turn to Barry for help finding a new Black Canary, or Barry will contact Oliver.

That said, since Guggenheim said 'Second Chances' will include the "fastest crossover," Oliver may simply enlist The Flash to retrieve Tina from Hub City - where she was introduced during the final moments of Arrow's midseason premiere - and bring her to Star City. No matter how The Flash appears in Arrow's upcoming episode, fans will likely appreciate the crossover as it reminds viewers the two shows exist in the same universe - and the heroes are friends as well as allies. But, as for how exactly The Flash will show up in 'Second Chances', we may need to wait for the episode to air to find out for certain.
