Both 'Arrow' and 'The Tomorrow People' fans were disappointed to find The CW's "Amellsdays" broken up by the latter's untimely cancellation, but a new day for the Amell cousins has dawned. Robbie Amell, kin to 'Arrow''s leading man Stephen, will return to the CW to join spinoff series 'The Flash' as an incarnation of DC superhero Firestorm!

From The Hollywood Reporter, Amell will appear beginning with 'The Flash''s third episode as Ronnie Raymond, one half of the fused pairing that made up comic hero Firestorm. In the CW's incarnation at least, Ronnie will emerge as Caitlin Snow's (Danielle Panabaker) fiance, a maintenance worker at S.T.A.R. Labs who played an integral part in the particle accelerator accident that transformed Barry Allen (Grant Gustin) into the Flash. As you'll see in the pilot, there's a spoiler-y reason something seems amiss about Ronnie's return.

Said producer Greg Berlanti of the character's inclusion in the series:

Geoff Johns, Andrew Kreisberg and myself designed the pilot and series to include Ronnie (aka Firestorm) — and to actually have someone with Robbie's talent playing the role is beyond exciting. We can't wait for viewers and fans of the character to check it out.

Added Amell:

I'm so excited to join forces with Greg Berlanti and The CW again on The Flash. Being brought into the DC Universe is a dream, I can't wait to get started!

Greenlit for (at least) 13 episodes, ‘The Flash’ also boasts among its cast Tom Cavanaugh’s Dr. Harrison Wells, Candice Batton's Iris West and Carlos Valdes’ Cisco RamonJesse L. Martin’s Detective West, ‘The Vampire Diaries‘ star Rick Cosnett as Central City Police transfer Detective Eddie Thawne, and original ‘Flash’ star John Wesley Shipp as Barry’s father Henry Allen. Amell's cousin (and 'Arrow''s Oliver Queen) Stephen will drop by the pilot episode at least, but future crossover between the two will remain to be seen.

I suppose we'll have to hold out hope of seeing the Amells sharing a screen one day, but what say you? Does 'The Flash' have your attention inflamed with the addition of Robbie Amell's Firestorm? Tell us in the comments what you want to to see when either DC series hits Comic-Con 2014!
