Last week, The CW's hit superhero show The Flash finally returned from its holiday mid-season hiatus with the new episode 'Borrowing Problems From the Future.' As fans get ready for this week's episode, 'Dead Or Alive,' airing Tuesday, January 31 at 8 PM ET, a new poster has been uncovered, which features Grant Gustin and Keiynan Lonsdale, who are both suited up as The Flash and Kid Flash. While this poster doesn't seem to be tied to a particular episode, it comes with the tagline "Lightning strikes twice."

The poster was revealed on Twitter by The Flash Brasil, showing both of these speedsters teaming up together. While this certainly isn't the first time Barry Allen has gotten help from another speedster, with Jay Garrick (Teddy Sears) and Jesse Quick (Violet Beane) lending a hand at times, they are both tied to different dimensions. With Wally West's emergence as Kid Flash, Barry may now have a true partner to take on all of the criminal elements in Central City, although their partnership didn't get off to the best start. This poster could reveal that a brighter future is ahead for both of these heroes teaming up together.

The synopsis for tomorrow's episode doesn't indicate that Kid Flash will have a large presence, but it's still possible that he may show up. Barry Allen (Grant Gustin) and Cisco Ramon (Carlos Valdes) must work together to save Harrison Wells (Tom Cavanagh) from an inter-dimensional bounty hunter who seeks to kill him, as it is a crime on Earth-19 to transport yourself to another earth. Cisco and Barry must fight against the bounty hunter in a fight to the death to save Harrison's life. It was also recently confirmed when the show's musical crossover with Supergirl will take place.

Earlier this month, it was confirmed that the musical crossover between Flash and Supergirl will air over two episodes, starting with Supergirl's March 20 episode, with the crossover starting towards the end of that episode, and the majority of this story being told in the Tuesday, March 21 episode of The Flash. It has previously been confirmed that The Music Meister will be the villain for this crossover, who, in the DC Comics, has the power to control his victims through song. Other CW stars who will be involved in musical performances include The Flash's Jesse L. Martin and Carlos Valdes, Legends of Tomorrow stars Victor Garber and John Barrowman and Supergirl's Jeremy Jordan. Supergirl's David Harewood and Chris Wood will also have non-singing guest star appearances.

The Flash was already renewed for Season 4 by The CW earlier this month, and another recent report confirmed that one beloved character is coming back from the dead, so to speak. Rick Cosnett, who played Detective Eddie Thawne in the first season of the hit series, confirmed on Twitter that he is returning to the show. Eddie sacrificed himself in the Season 1 finale, but he returned in The Flash Season 2 episode "Flash Back," which aired last March. That episode followed Barry Allen (Grant Gustin) as he traveled back in time to consult with Eobard Thawne. While he was there, Barry managed to coax Eddie Thawne into a recording a "goodbye" message to Iris West (Candice Patton), who was still mourning her late fiancee's death. Take a look at this new poster for The Flash Season 3 below.
