Well, we finally get a brief look at Grant Gustin in action as forensic scientist Barry Allen, the man who will, hopefully, one day become the live action Flash not just on TV but maybe even in the movies.  The character will debut on the December 4th episode of ‘Arrow’ as part of the two-episode mid-season finale.  (When did this become a thing?)

But as previously was revealed, Barry comes to Starling City to help with a case that has “unexplained elements” which mirror a case he previously worked on in Central City.  According to the clip, it appears that Felicity Smoak (Emily Bett Rickards) may already know of the character before he is summoned to Starling City.  And producers have implied that sparks might fly between the two tech geek characters.  (This may upset Ollie/Felicity shippers!)

On a side note, it also sounds like the Sebastian “Brother” Blood storyline will play a large part in this plot evolution.  You can watch the clip below:

Okay, yeah Barry was barely in it, but consider it a teaser.  Surely, his role will be much beefier in the actual episode.  But it’s a glimpse of what’s to come.  It may be too early to judge, but what based on this clip, are you sold on Grant Gustin as Barry Allen?  Do you think he can anchor his own series… or a film?
