Six months later, Barry operates alone, using his speed to repair Central City while being embraced by the public as a hero; Cisco works in the police department alongside Joe, and Caitlin works at Mercury Labs. Barry evaluates a crime scene with a victim named Al Rothstein. At a ceremony, the Flash is attacked by Atom-Smasher, whose strength and size manipulation prove too much for Barry, who forces his mask off. Underneath the mask, Atom-Smasher is revealed to look exactly like Rothstein. Barry is convinced by Joe and the others that he needs help in taking down certain metahumans and Rothstein is defeated by over absorbing radiation. While dying, Rothstein tells Barry that he was sent to kill him by someone called "Zoom". Barry receives a flash memory from Harrison Wells' (Eobard Thawne) lawyer containing his confession to killing Nora. Henry is exonerated and released from prison, and leaves Central City so that Barry can focus on being the Flash. A man arrives at S.T.A.R. Labs, introduces himself as Jay Garrick and tells the team that their world is in danger. |LineColor = 1D2229 }} {{Episode list/sublist|The Flash season 2 |EpisodeNumber = 25 |EpisodeNumber2 = 2 |Title = Flash of Two Worlds |DirectedBy = Jesse Warn |WrittenBy = Aaron Helbing & Todd Helbing |OriginalAirDate = {{Start date|2015|10|13}} |ProdCode = 3J5652 |Viewers = 3.49<ref name="2.02">{{Cite web |url=http://tvbythenumbers.zap2it.com/2015/10/14/tuesday-final-ratings-oct-13-2015/478601/ |title=Tuesday final ratings: 'The Flash' and 'NCIS' adjusted up, 'Chicago Fire' holds |last=Porter |first=Rick |date=October 14, 2015 |website=TV by the Numbers |url-status=dead |archive-url=https://web.archive.org/web/20151016101118/http://tvbythenumbers.zap2it.com/2015/10/14/tuesday-final-ratings-oct-13-2015/478601/ |archive-date=October 16, 2015 |access-date=October 14, 2015 }}</ref> |ShortSummary = Jay explains to everyone that he is the Flash on a parallel Earth and that he was in a battle with a demonic speedster named Zoom when the singularity brought him to this Earth without his powers.

Cisco analyzes the "sand" left behind and has a vision of the previous fight, frightening him. After Slick kidnaps Officer Patty Spivot, Jay teaches Barry how to hurl lightning. Cisco uses his power to find Patty's location. Barry uses the lightning blast to turn Sand Demon's particles to glass, killing him. Patty reveals to Joe that Mark Mardon killed her father.

Lisa states that Snart would never work with Lewis willingly, because the latter was abusive toward her when she was a child. Eventually, the team determines that Lewis placed a bomb inside of Lisa and threatened to kill her if Snart did not help him with his theft. Barry infiltrates Lewis' crew with assistance from Snart.

Discussing the casting of Lonsdale, Kreisberg stated, "Just like when we met Grant [Gustin] for the first time, we instantly knew Keiynan embodied all the heart and courage of a hero. We are so excited to be bringing this much-beloved character onto the show."<ref name="WallyFlashS2" /> It was always intended for Wally to be the son of Joe and brother of Iris, which differs from the character's comic history, as the producers disliked second seasons of television series that would introduce cousins of characters that were never previously mentioned, feeling it was "weird".<ref name="KreisbergOct2015" /> Lonsdale originally auditioned for ''Legends of Tomorrow'' to portray Jefferson "Jax" Jackson.<ref>{{Cite magazine |url=https://www.ew.com/article/2015/12/07/flash-wally-west-lonsdale-martin |title=The Flash stars talk Wally West introduction |last=Abrams |first=Natalie |date=December 7, 2015 |magazine=Entertainment Weekly |url-status=live |archive-url=https://web.archive.org/web/20151209082111/http://www.ew.com/article/2015/12/07/flash-wally-west-lonsdale-martin |archive-date=December 9, 2015 |access-date=December 8, 2015}}</ref>

The crossover episode received excellent reviews. Cliff Wheatley of IGN gave the episode an 8.6/10, stating "After the grim 'n' gritty ''Batman v Superman'', ''Supergirl''{{'s}} "Worlds Finest" offered a fun, upbeat palette cleanser and one of the series' strongest episodes to date. Instead of the usual "beatdown" introduction, Supergirl and the Flash went straight to being superfriends, which was refreshing. Not only did Barry Allen fit perfectly in Kara's world, but actors Grant Gustin and Melissa Benoist had fantastic chemistry together onscreen.

Reviewing the season finale, Allison Keene of Collider directed specific praise to Gustin's performance, saying "Sometimes a great TV performer can come out of an already fantastic episode, but occasionally an actor can rise above the material, proving that even though the writers have let them down, the actor is going to make the most of what they've been given. That's exactly where we find ourselves with ''The Flash''{{'}}s head-scratching finale, which capped off a largely enjoyable but ultimately uneven second season. What has never been in doubt, though, is star Grant Gustin's ability to convince viewers that this all makes sense in an emotional, earnest, and often light-hearted way."<ref>{{Cite web |url=https://collider.com/tv-performer-of-the-week-grant-gustin-the-flash/ |title=TV Performer of the Week: Grant Gustin, 'The Flash' |last=Keene |first=Allison |date=May 27, 2016 |website=Collider |url-status=live |archive-url=https://web.archive.org/web/20181216104238/http://collider.com/tv-performer-of-the-week-grant-gustin-the-flash |archive-date=December 16, 2018 |access-date=December 16, 2018}}</ref> In his review for ''Nerdist'', Joseph McCabe concluded, "For all this season's faults, most of which came from repeating the major villain arc of season one, [...] there were moments in the last handful of episodes where Barry demonstrated more independent thought than the show often allows him. Coming up with his own ideas, for example, to defeat the villain of the week rather than relying on his friends at S.T.A.R. Labs. That's the Barry I want to see more of in season three.<ref>{{Cite web |url=https://archive.nerdist.com/the-flash-season-finale-review-the-race-of-his-life/ |title=THE FLASH SEASON FINALE REVIEW: "THE RACE OF HIS LIFE" |last=McCabe |first=Joseph |date=May 25, 2016 |website=Nerdist |url-status=live |archive-url=https://web.archive.org/web/20181218054847/https://nerdist.com/the-flash-season-finale-review-the-race-of-his-life/ |archive-date=December 18, 2018 |access-date=December 17, 2018 }}</ref>

A number of critics felt that the season as a whole suffered from the standards set by its predecessor, calling it "uneven" and criticizing the handling of the season's main villain. Collider's Kayti Burt gave the season 3 stars out of 5, saying, "''The Flash'' finished off an uneven season with an uneven finale that couldn't overcome the burden of an underdeveloped, illogical villain. With Zoom, ''The Flash'' fell victim to a common drama mistake of a contemporary TV era: it prioritized the plot twist over the well-developed character arc."<ref>{{Cite web |url=https://collider.com/the-flash-season-2-finale-recap-the-race-of-his-life/ |title='The Flash' Season 2 Finale Recap: "The Race of His Life" |last=Burt |first=Kayti |date=May 24, 2016 |website=Collider |url-status=live |archive-url=https://web.archive.org/web/20180407033532/http://collider.com/the-flash-season-2-finale-recap-the-race-of-his-life |archive-date=April 7, 2018 |access-date=December 16, 2018}}</ref> Jeff Jensen of ''Entertainment Weekly'' gave the season a "B−" grade, calling it "certifiably slumptacular" and said that the "bold" introduction of the multiverse did not meet his expectations. Jensen praised Barry's onscreen rapport with Joe but felt it was underutilized due to the introduction of Joe's biological son Wally, and criticized Barry's romantic fixation for Iris. He also criticized Zoom, saying, "He began as an alluring mystery but lost zip over time" and once his identity was revealed, "became a weak embodiment of generic villainy".<ref>{{Cite magazine |url=https://ew.com/article/2016/05/25/flash-season-2-review/ |title=The Flash season 2 review |last=Jensen |first=Jeff |date=March 28, 2017 |magazine=Entertainment Weekly |access-date=December 2, 2018 |url-status=live |archive-url=https://web.archive.org/web/20181215090244/https://ew.com/article/2016/05/25/flash-season-2-review/ |archive-date=December 15, 2018}}</ref> Jesse Schedeen gave the entire season a rating of 8.6 out of 10, explaining, "This season met and occasionally even exceeded the heights of its predecessor.
