CW's The Flash was a breakout hit in its freshman season, and its biggest accomplishment was arguably opening the door of possibilities for the DC TV Multiverse - far wider than the "no powers" and "grounded and gritty" policies of Arrow ever allowed. Flash ended season 1 on a big cliffhanger with our hero trying to stop a singularity event from destroying Central City - a space/time maelstrom that Flash himself caused by jaunting back through time in failed attempt to save his mother.
When The Flash season 2 returns, there are a list of things we want to see occur, but the one with the richest possibilities is how the show can now use the established concepts of The Speed Force, time travel and multiverse theory to really play with the arrangement of characters on the show, while offering possibility for new characters (or new spins on familiar characters) to join the party. The latest Flash season 2 trailer above (and interview with executive producer Andrew Kriesberg below) points to one clear fact: the showrunners will be fully utilizing the multiverse of possibilities out there.
It doesn't get more on the nose than a trailer titled "Other Worlds" to let you know that season 2 of the Flash will use the time travel experience and singularity event to set loose some good multiverse mayhem to play with. But for those who didn't get it just from reading the trailer title, the actual footage included pretty much hammers the point home, with a new mystery sprinkled in (the machinations of Professor Zoom); new heroes and villains being teased (Atom Smasher, Jesse Quick) and fan-favorite characters like Golden Glider, Captain Cold, Heatwave and a new version of Harrison Wells all coming back, as well.
As for what other new things we'll see in season 2, here's what Flash executive producer Andrew Kriesberg had to say on several subjects:
(New human cop ally / love interest - Played by The Final Destination star Shantel VanSanten)
Andrew Kriesberg: "She’s got a very specific reason for wanting to fight metahumans, which we’ll learn about during the course of the season. She’s a science nerd, too. She really loves the science aspect of it, and she and Barry really bond on that level, but she also loves the action... She earns her metahuman fighting stripes in the second episode. One of the cool things about Patty is it’s one thing to take on bank robbers, it’s another to take on someone who can turn into poison gas, or another guy who can control the weather. At a key moment early on, Patty is the only cop who stands her ground, and that proves to Joe that she’s got what it takes.”
(Flash from a parallel dimension - Played by Masters of Sex actor Teddy Sears.)
AK: “There’s a little condescension from Jay. Jay is a little bit more world-weary and he’s seen a lot. He’s been The Flash for a while, so he’s a little further along in his career. He’s seen a lot of darkness, and it’s jaded him a little bit. He thinks Barry can be a bit naïve about the way the world works... One of Barry’s greatest gifts — and truly it’s one of Grant’s greatest gifts, too — is he’s got such an infectious energy and such a purity of heart that he makes you want to be a better person. As much as Barry learns from Jay about being The Flash, Jay learns just as much about being a good person from Barry." (Played by Masters of Sex actor Teddy Sears.)
(Eventual "Kid Flash" - Played by Insurgent actor Keiyan Lonsdale.)
AK: “I would liken Wally coming in to the way we brought on Colton Haynes on toArrow. Just like with Colton Haynes, who eventually one day put on the Arsenal costume, I wouldn’t be surprised if one day Wally West becomes Kid Flash... Part of the season is watching Barry mature and grow up not just as The Flash, but as Barry Allen. Suddenly introducing him to a bit of a wayward kid who has some attitude problems and some authority issues and is quick with a sassy remark — all of which is very Wally West — and then watching Wally integrate into S.T.A.R. Labs universe, but also just the world of these characters, is going to be a lot of the fun of the back half of the year.”
(Ominous new Speedster "Big Bad" - Voiced by Candyman icon Tony Todd; physical actor TBD.)
AK: “We wanted another speedster as a villain, but we wanted to do something slightly different. Reverse Flash felt like a warrior, and what we wanted this time was something more akin to a monster. When you finally see Zoom, he looks like a demon, and it’s really scary. It’s more horrific. You should feel like when one of H.R. Giger’s aliens comes in the room. The mask is really amazing... Like with Wells last year, he has a very specific agenda and a very specific and very clean reason for doing what he’s doing. When we open the season, he’s a villain of Earth-Two, and now he has access to Earth-One. Yet again, our team has created their own nemeses for the season. Watching how Zoom enacts his plan is the plot of the first nine episodes.
Season 2 of The Flash premieres Tuesday, October 6 at 8pm/7 central; Season 4 of Arrow debuts Wednesday October 7 at 8pm/7 central; Legends of Tomorrow begins in 2016.
