Felicity & Helix Hunt Adrian Chase in New Arrow Promo

The last episode of "Arrow" concluded with district attorney Adrian Chase escaping from the police after his identity as Prometheus was revealed. Now, the SCPD, ARGUS and Team Arrow are on a manhunt to find the Season 5 villain in the upcoming episode titled "Dangerous Liaisons."

In the promo for the episode, Felicity decides to take matters into her own hands -- or more specifically, her and Helix's hands. Rather than working together with her fellow Team Arrow companions, Felicity has partnered with the hacker organization to take down Prometheus, who is responsible for the death of her boyfriend Billy Malone.

The trailer features brief action sequences of the team suited up and shows Oliver asking Felicity, "Don't do this." It ends with Felicity sternly responding, "You'll have to stop me."

As Season 5 nears its finale, we've learned of more and more familiar faces returning to the show who will play a role in Oliver's attempts to stop Chase. Katrina Law will return as Nyssa al Ghul for a few episodes that will culminate in a showdown against her half sister Talia.

Airing Wednesdays at 8 p.m. ET/PT on The CW, "Arrow" stars Stephen Amell, Emily Bett Rickards, David Ramsey, Willa Holland, Paul Blackthorne and Echo Callum.
