The high-rated TV series "The Flash" has had many wonderful episodes in their first season and this season 2. Now, the series is almost at its 13^th episode and stories are unfolding fast. So, what's going to happen on "The Flash" episode 13?

If the released teaser trailer is right, then Barry (Grant Gustin), Cisco (Carlos Valdes) is going to travel across the multiverse together with Harrison Wells (Tom Cavanagh) to Earth-2. The reason why the trio of is going to travel to Earth-2 is because they will try to save Well's daughter, Jesse (Violett Beane) from villain, Zoom (Tony Todd).

"We want to thank Grant Gustin for making the time to come visit (on top of his already immense workload) and all of the folks at CBS, The CW, Warner Bros. and DC for working this out."
