New Arrow Clip Introduces Us To Flash's Danielle Panabaker And Carlos Valdes

The video below includes a look at the set and interviews with the cast of Arrow. At about the 3:15 mark, you'll find a clip from tonight's episode, "The Man Under the Hood," which gives us a nice introduction to guest stars Danielle Panabaker and Carlos Valde, who are set to be featured in the Flash pilot.

Arrow took a week off after battling "Deathstroke" and The CW has been taking advantage of the extra time between episodes to promote tomorrow night's return. The network already released a trailer for and clip from the highly anticipated "The Man Under the Hood" and now, the new 'DC All Access' not only shows what goes on behind the scenes of the superhero series but also the installment's introduction of two characters who will play a pivotal part in the Flash spin-off.

The time spent with the cast on set is your standard behind-the-scenes stuff as the interviewer, Tiffany Smith, keeps it light with comments about Stephen Amell's penchant for being shirtless as well as several other Arrow related quizzes. There are also the usual vague questions about what we can expect from upcoming episodes, including whether or not the second season finale will be epic (imagine executive producer Andrew Kriesberg said no?), but the real meat of the video comes at the 3.15 mark.

The 'DC All Access' 'exclusive' from "The Man Under the Hood" may not be as action packed as the previous promos but simply seeing Danielle Panabaker and Carlos Valdes on Arrow is exciting enough. And this time they actually speak. For those who don't know, Panabaker will be playing Caitlin Snow, who eventually becomes the supervillain Killer Frost, while Valdes is Cisco Ramon, who eventually becomes the superhero Vibe.

In the clip, the two new characters are charged with cleaning up the Starling City branch of S.T.A.R. Labs after the disastrous Central City particle accelerator explosion killed a lot of people and left others in a coma. It looks like Panabaker's Snow lost someone important to her during the blast and perhaps that's how the writers plan to turn her bad. If that's the plan. They also manage to instantly make Valdes' Ramon appear sympathetic and helpful, perfect for his planned sidekick role on Flash. You know, if that's the plan.

During the discussion of all the cool things the scientists have stored in the facility (uh oh), Ramon name drops (Tom Cavanagh's) Dr. Wells before asking his co-worker if the security guard is giving off a bad 'vibe.' Clever. Of course, the reason for the bad vibes is that the guard is essentially just a standing corpse thanks to Deathstroke, who is conveniently hidden behind. So, what's he going to steal from the storage facility? He already has the mirakuru. Find out when...

Arrow returns with Episode 19, "The Man Under the Hood," tomorrow at 8 p.m. ET on The CW. Created by Marc Guggenheim, Andrew Kreisberg and Greg Berlanti, the DC Comics inspired series stars Stephen Amell, Katie Cassidy, David Ramsey, Emily Bett Rickards, Willa Holland, Colton Haynes, Manu Bennett, Paul Blackthorne and Susanna Thompson.
