This week The Flash gets its second Arrow crossover on The CW in less than a month.

'The Originals' Gets New The 'Vampire Diaries' Crossover With Nina Dobrev

The Flash kicked off its CW debut with a guest-appearance from Arrow's Stephen Amell, but this week the new CW drama will be getting yet another crossover when Emily Bert Rickards steps in as Felicity Smoak.

"My team has a similar set-up, but with more pointy objects," she declares when Barry Allen (Grant Gustin) introduces her as a friend of "The Arrow" during the new program's latest preview (featured below).

Gustin was first introduced as Barry on Arrow before The Flash became its own series and so the crossover is only natural.

While Smoak is the biggest addition to the series this week, she's not the only one. Also making his debut on The Flash Tuesday is Wentworth Miller, who will be playing the "meta-human" Leonard Snart. Miller is best known for his role on Fox's Prison Break and fans of the crime drama will get a second treat this season when Miller's Prison Break costar Dominic Purcell appears as Snart's meta-human ally Heat Wave.

As the network's highest-rated debut since The Vampire Diaries in 2009, The Flash quickly got a full season order from The CW which has opened the series up to more opportunities to play around with form.

According to Digital Spy, The Flash and Arrow aren't done teaming up. The shows will have another two-part crossover event later this season, which means Central City might not have seen the last of Felicity.

While both programs exist within the same world and include many of the same characters, Gustin insists that each has something different to offer.

"I think it's just less apologetic for what it is than Arrow…" explained Gustine of The Flash in an interview with Digital Spy on Monday. "Righty out of the gates, we are what we are, this is The Flash. He is a superhero, this is a comic book, and we're embracing it and enjoying it."

The Flash continues on The CW with its first season Tuesdays at 8 p.m. ET/PT.
