Flash, Vibe, and Killer Frost to debut in Arrow?

When the first rumblings of the proposed Flash TV show hit, fans knew that Arrow would be getting a “Back Door” pilot to the show late in its second season, but when the initial episode debuting Barry Allen hit and the ratings went through the roof, the CW greenlit the show without need of that pilot.

Now it seems though, regardless of the plans of scrubbing that backdoor pilot, we will still be seeing that episode in some form this season.

Spoiler TV have posted a call sheet for episode 19 of Arrow, which includes several characters that were said to be involved in the Flash TV show primarily:

Stephen Amell – Oliver Queen/Arrow 
Simon Burnett – Oliver Stunt Dbl. 
Katie Cassidy – Laurel Lance 
David Ramsey – John Diggle 
Emily Bett Rickards – Felicity Smoak 
James Michealopoulos – Deathstroke Stunt Dbl. 
Atlin Mitchell – Sara Lance/Canary (probably a double) 
Danielle Panabaker – Caitlin Snow
Carlos Valdez – Cisco Ramon 
JJ Makaro – Stunt Coordinator 
James Bamford – Fight Coordinator 
Hugo Steele – Security Guard #2 
Colton Haynes – Roy Harper 
Manu Bennett – Slade Wilson 
Summer Glau – Isabel Rochev

No word yet on if this post is legitimate or not, but with the title being currently listed as “The Man Under the Hood” I for one am now seriously looking forward to seeing that episode now.
