If you haven't already watched this week's episode of "The Flash", then spoiler alert! Proceed at your own risk.

As Teddy Sears's Jay Garrick explained on the show, he is The Flash from another world --- an Earth 2, as they put it. However, his is not the only earth in the series, as explained in the last episode, there are 52 others, so you can bet that it's going to be a bit confusing. However, what's not confusing is the fact that Jay Garrick's flash has a major baddie named Zoom and it looks like he's also after Barry Allen (portrayed by Grant Gustin).

In an interview with E! News, Sears said about Zoom, "He's the worst. He is TERRIBLE. He truly is evil incarnate. He's the perfect villain for season two." He already sent Atom-Smasher to kill Barry in the season's premiere, followed closely by Sand Demon and probably a bunch more metahumans down the line. However, what do we really know of Zoom?

As explained on the show, Zoom is a speedster obsessed with being the only one around, in any and every dimension. Other than that, What Culture explained that the villain, who is voiced by Tony Todd has not shown himself yet, although there is a possibility as who it could be.

In the last scene for episode 2, Harrison Wells of Earth 2 is definitely alive and well, and if he's as evil as Barry's mentor, there is a possibility that Zoom is Earth 2's version of Reverse Flash. After all, as What Culture noted, Tony Todd merely voiced the supervillain, the physical identity is yet to be revealed. Of course, there could be another Zoom entirely, after all, Barry Allen isn't Earth 2's speedster, right? In the comics, as noted by Bustle, Eobard Thawne is also Professor Zoom, but the series could go a different way. Until CW reveals the new supervillain, all fans can do for now is take a guess.

There was a lot that went on in this week's episode, for instance, "One Tree Hill" actress Shantel Vantansen shows up as an eager cop ready to take on the metahuman task force, ending up as Joe's new partner.

On a final note, Iris's mom showed up as well. She's been MIA up to now, so does that mean that she have a significant role in the show? Sears told E! News that a lot of the characters will have their own stories now, which could include Iris and Joe, and Cisco, whose powers (which were revealed last season) is more apparent now more than ever.

Don't miss out on the next episode, "The Flash" airs Tuesday nights on The CW.
