Expect to see a wet and wild episode of "The Flash" when it returns for the 15^th episode of season 2.

The upcoming episode will feature the visit of Team Arrow's John Diggle (David Ramsey) and his wife Lyla (Audrey Marie Anderson) to Central City from Star City to warn The Flash (Grant Gustin) and the rest of Team Flash about the return of the meta-human named King Shark after escaping his holding tank in A.R.G.U.S.

Fans of the series first encountered King Shark in episode 4, after the flesh-eating half-man half-fish monster was commissioned by Zoom (Tony Todd) to kill Barry Allen/The Flash but his mission failed and he was captured. He also caused a lot of trouble for Oliver Queen's (Stephen Amell) team on "Arrow," and is reportedly threatening to cause more chaos as it finds its way back to Central City.

But it seems like King Shark will have a little detour before attacking his target. As seen in the trailer for the upcoming episode, the creature will head first toward the West's house and attack Barry and Joe (Jesse L. Martin), Iris (Candice Patton), and Wally (Keiynan Lonsdale).

However, The Flash and the rest of the team are prepared to face King Shark this time. According to the promo, The Flash will be eagerly waiting for his water-based opponent at the docks so he can finally defeat it and put it back in the enclosed aquarium.

Meanwhile, fans of the show would like to find out if Jay Garrick (Teddy Sears) is really dead after Zoom stabbed him in the chest and pulled him toward the portal that separates Earth-1 and Earth-2. This obviously hurt Caitlin Snow (Danielle Panabaker), whose first love was also killed right before her eyes. Will the episode shed light on the fate of Earth-2's Flash?

"The Flash" season 2 episode 15 airs Tuesday, Feb. 23, on The CW.
