Robbie Amell officially signs in to guest star in the upcoming episode of "The Flash" Season 2. According to Fashion & Style, Amell will reprise his role with a twist and he will debut as Earth-2 Ronnie Raymond (aka Deathstorm) doppleganger. The 27-year-old Canadian actor also teased that Earth-2 Ronnie will kill one of the main characters of the series.

With that being said, rumor has it that Amell is talking about none other than Teddy Sears' character, Jay Garrick. The rumor stemmed since Sears is one of the show's newest main characters and they've only begun to explore Jay's story just yet, as reported by Buddy TV.

As for the official plot of Season 2's episode 13, We Got This Covered notes, "Barry visits Earth-2. Barry (Grant Gustin), Wells (Tom Cavanagh), and Cisco (Carlos Valdes) journey to Earth-2 to rescue Wells' daughter, Jesse (guest star) from Zoom. Barry is stunned when he runs into Earth-2 Iris (Candice Patton) and Joe (Jesse L. Martin), but nothing prepares him for meeting Killer Frost (Danielle Panabaker) and Deathstorm (guest star Robbie Amell).

Meanwhile, back on Earth-1, Jay (guest star Teddy Sears) has to take over the Flash's (guest star Adam Stafford) responsibilities when a meta-human nicknamed Geomancer attacks Central City."
