"The Flash" season 2 will feature a new theory of Zoom's true identity and a leaked trailer featuring Earth 2 Linda Park as Doctor Light.

A leaked Australian promo for episode 5 of "The Flash" season 2, "The Darkness and the Light" features the appearance of Earth 2 Doctor Light as she is sent by Zoom (Tony Todd) to kill Barry Allen/The Flash. But what is interesting about the trailer is that this version of Doctor Light is female and it is not Kimiho Yoshi, but rather the Earth 2 doppelganger of Linda Park (Malese Jow), The Christian Post reported.

Comic book fans and audiences may remember Linda Park is Barry's ex-girlfriend in season 1 and as the episode will likely center on her since Doctor Light is her Earth 2 counterpart. Episode 5 will also feature the return of Harrison Wells (Tom Cavanagh) to Team Flash, but this version of Wells in from Earth 2 and is seeking their help to stop Zoom and it is revealed to be responsible for his creation.

The real Harrison Wells was killed by Eobard Thawne/Reverse-Flash (Matt Letscher) in season 1 and created the particle accelerator that caused everyone in Central City to become Metahumans. Seeing Wells back on the team could add huge drama and tension to the show, especially on Cisco Ramon (Carlos Valdes), Caitlin Snow (Danielle Panabaker) and even Barry Allen.

In other news, the latest theory on Zoom's true identity will involve three characters in the comics, Moviepilot reported.

These characters are identified as Daniel West, Future Barry Allen and Eobard Thawne. Both Future Barry Allen and Eobard Thawne have been heavily theorized by comic book fans seeing as Future Barry had a blue costume and lightning energy coming out it and Eddie body being sucked into the singularity in the season 1 finale, leaving his faith unknown in the show.

Daniel West first appeared in the New 52 DC comics as the estrange brother of Iris West and latest incarnation of Reverse-Flash. With the revelation that Joe West (Jesse L. Martin) had a son with Francine (Vanessa A. Williams) that he did not know about, it speculated that Wally West (Keiynan Lonsdale) could be Joe son and Iris' (Candice Patton) brother in the show, but it is not yet confirmed at the moment until he appear in the mid-season finale.

Other theories suggest that Zoom could be Earth 2 Wally West, but since Daniel is the only West family member who has a grudge with his family and The Flash in the comics, it is safe to assume that Daniel could possibly be Zoom.

The Flash airs on Tuesdays at 8pm ET on The CW Network.
