When "The Flash" returns this October with its second season, there will be plenty of new characters on the hit CW series -- most of which have firm roots in DC Comics history. Notably, Wally West and Jay Garrick -- both former Flashes in comic book lore -- will make their live-action TV debuts, played by Keiynan Lonsdale and Teddy Sears, respectively. In a new interview with Entertainment Weekly, "Flash" executive producer Andrew Kreisberg shared insight on both characters.

Notably, Kreisberg said there's a chance that the TV Wally West will follow in the (fast) footsteps of the comic book Wally West and become Kid Flash (even though Lonsdale and star Grant Gustin are only two years apart in age). The EP compared it to Colton Haynes joining "Arrow," and eventually adopting the Arsenal identity. "Part of the season is watching Barry mature and grow up not just as The Flash, but as Barry Allen," Kreisberg told EW. "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."

Kreisberg also gave a hint of the Jay Garrick/Barry Allen dynamic. "Jay is a little bit more world-weary and he's seen a lot," Kreisberg said. "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."

Also coming to "The Flash" are mysterious new archvillain Zoom -- who Kreisberg described as looking "like a demon, and it's really scary" -- and Patty Spivot, played by Shantel VanSanten and a potential love interest for the title character. "She really loves the science aspect of it, and she and Barry really bond on that level, but she also loves the action."

"The Flash" season two is scheduled to debut Tuesday, Oct. 6. on The CW.
