It seems that after the events of season one of The Flash, Grant Gustin's Barry Allen will question whether he should continue his superhero career. Initially, Allen wanted to use his powers to help the Central City police stop other criminals who recieved their powers as a result of S.T.A.R. Labs particle accelerator explosion. From there, his motivation turned to clearing his father's name as the murderer of Barry's mother. However, by the end of season one, these goals took somewhat of a backseat to simply stopping Tom Cavanagh's Harrison Wells. But with Wells "seemingly" stopped for good, what's left for Barry to accomplish? The Flash producer Gabrielle Stanton touched on where Barry's head is at when the show kicks off season 2. "[Barry] went through a lot, at the end of last season. He’s definitely going to start this season with a step back and be like, “What am I doing? Why am I doing this?” If last season was the journey of Barry discovering he’s a hero, this season is definitely him trying to figure out what that means. What is it to be a hero? What does he need to be a hero? What is it going to do to his personal relationships?"
As for who will replace Wells as the mentor for Barry's superheroics; enter Jay Garrick as played by Teddy Sears. Stanton confirmed that , "...we’re introducing Jay Garrick, who will be a mentory character to Barry. Jay has seen some things that Barry hasn’t seen, and he’s going to be helping him through the process."
Going back to the final events of the first season of The Flash, Barry glimpsed a lot of things in the Speed Force, most notably Danielle Panabaker's transformation into the villainous Killer Frost. But if the Speed Force gave Barry a glimpse of things yet to come, how long will we have to wait to see the DC Comics villain? "It’s going to be a slower burn on that. That was just to keep people guessing. Who knows when Killer Frost is going to turn up? We did the helmet. We try to drop little Easter eggs. What I really like about The Flash is that I am a comic book fan, so I know a lot of this stuff, but my husband is not a comic book fan at all, and he still gets everything."
These questions and more will be answered when The Flash returns for season 2 on The CW on October 6th at 8PM.
