Will Grant Gustin Show Up As ‘The Flash’ During 'Arrow' Season Two Finale? CW Network Promises ‘Unthinkable’ Will Happen! [Watch Video]

The CW Network has released the promo logos for their newest TV series, The Flash. Now the CW is teasing the return of The Flash during Arrow's highly anticipated season two finale?

In the season two finale of Arrow, Slade Wilson, The Terminator, brings in his Deathstroke army to take over the city from Ollie Queen, the vigilante known as Arrow. Ollie, Black Canary, and his allies will go down fighting to save their troubled city. Will someone close to Ollie die in the episode or will he receive unexpected help?

Audiences were introduced to The Flash (played by Grant Gustin) in an earlier episode. Could the teaser mean that the Flash will show up again during the season two finale? We first saw the Flash without his superpowers and the red costume. This will be a different Barry Allen that Ollie meets this time around.

You have to admit the special effects and CGI looks promising. Remember, we have to believe The Flash is running at super-speed. Notice the smoke coming out of the Flash's boots as his running feet leave a trail of fire behind.

With the Deathstroke army, being led by Slade, Ollie Queen is going to need all the help he can get. Will The Flash lend a helping hand during the May 14 season two finale of Arrow?
