Season 2 of "The Flash" may have started on a sad note, but by the end of its premiere episode "The Man Who Saved Central City", Team Flash has accepted the fact that they need to move forward together.

However, the joy of working together as a team again was slightly tarnished by the fact that meta-humans from another time-space are being sent to get rid of Barry Allen aka The Flash (Grant Gustin).

The Flash is not completely alone in his battle against this new villain Zoom (Tony Todd), as his predecessor and the First Flash, Jay Garrick (Tedd Sears) has also travelled to Barry's time in order to prepare him for a battle against Zoom.

Although we fans know Jay to be a stand-up dude, he is still a stranger to Team Flash, and they will take time to cozy up to him. It will be a while before they can trust the meta-human that has just travelled through the singularity that Barry creates. After all, he could turn out to be part of a long con that Zoom is playing, much like his first nemesis The Reverse Flash (Tom Cavanaugh).

Regardless, we will see them working together, and Jay revealing to Barry that where he comes from, he is the Flash. He also tells Barry that Zoom would go to any lengths to ensure that he is the only speedster in any world and agrees to train Barry in preparation for battle against Zoom.

Jay's mentorship will go a long way with Barry, because he is literally the first person Barry can sit down and talk with, about being a speedster. "It's not like he go have drinks with Wells and talk about being a speedster, but he can with Jay, and Jay can mentor him on some of the powers that he has and figure out the best way to get him to use those," explains Todd Helbing to IGN.

Tedd Sears also clarified that Barry's relationship with Jay will resemble an older and younger brother dynamic "...there are some things you can only talk to an older sibling about that you maybe wouldn't feel comfortable talking to a dad character about." The writer and the newly-appointed actor also spoke about how much everybody loves Grant and Sears further confirmed that his love for Grant will be translated on screen as well.
