A good deal of the second season of The Flash so far was dedicated to setting up or positioning certain characters so that they could appear in The CW's newest addition to its shared DC Comics universe, Legends of Tomorrow. The Flash introduced Kendra Saunders a.k.a. Hawkgirl (Ciara Renée) -- as well as Vandal Savage (Casper Crump) and Carter Hall a.k.a. Hawkman (Falk Hentschel) in the show's crossover with Arrow -- plus broke Captain Cold (Wentworth Miller) out of prison and found Martin Stein (Victor Garber) a new half to his metahuman alter-ego Firestorm in Jefferson Jackson (Franz Drameh).
However, season 2 also introduced fans of The Flash to the show's multiverse, and more specifically, Earth-2. Now in the second half of The Flash's second season, the show will be dealing more with Earth-2 villains, as showcased in a new extended trailer for the series' midseason premiere.
The CW released the extended trailer (above) with the title 'Pretty Messed Up', which teases that "everything you thought you knew will change." The trailer focuses on Barry Allen's (Grant Gustin) major antagonist of season 2, Zoom (voiced by Tony Todd). Additionally, the trailer highlights the return of Eobard Thawne a.k.a. Reverse-Flash (Matt Letscher), as well as Earth-2 versions of Caitlin Snow (Danielle Panabaker) and Ronnie Raymond (Robbie Amell) who are the villains Killer Frost and Deathstorm.
Both Earth-1 and Earth-2 versions of other characters appear in the trailer as well; Joe West (Jesse L. Martin) can be seen talking to his recently discovered estranged son Wally (Keiynan Lonsdale). An Earth-2 iteration of Iris West (Candice Patton) is shown with that reality's Barry. Plus, Dr. Harrison Wells (Tom Cavanagh) opens the trailer with a chilling line: "Barry Allen, they call him the fastest man alive; he is not. That honor belongs to Zoom." While Cisco Ramon (Carlos Valdes) gets his trademark snarky comment in at the end: "Good luck fixing the universe." Additionally featured is Earth-2’s version of The Flash, Jay Garrick (Teddy Sears).
With Legends of Tomorrow officially spinning off into its own series, showrunner Andrew Kreisberg previously said the rest of The Flash season 2 will focus on Central City and Barry's struggle with the multiverse. This is further proved with the new extended trailer for The Flash's midseason premiere, which shows a major shift to be entirely about the breaches between Earth-1 and Earth-2 as well as the characters Team Flash will face as a result. Fans hoping to see less focus on Legends of Tomorrow are sure to welcome this shift.
Of course, although this newest trailer highlights a storyline concentrated on Central City, The Flash still has crossover plans -- though they're on a much smaller scale than the show's annual event. John Diggle (David Ramsey) and Lyla Michaels (Audrey Marie Anderson) will be heading to Central City in pursuit of King Shark, which will likely offer fans a small respite from Zoom. But, for the most part, it seems the back half of The Flash season 2 will keep its storylines focused on the S.T.A.R. Labs team and their dealings with the multiverse - especially Zoom.
The Flash will return on Tuesday, January 19, 2016, while Arrow will return on Wednesday, January 20, 2016 and Legends of Tomorrow will see its series premiere on Thursday, January 21, 2016.
