Tonight's episode of Arrow, "Nanda Parbat", features the debut of Brandon Routh's Ray Palmer as his superhero alter-ego Atom. The CW has released a new preview from "Nanda Parbat", which features new footage of Felicity Smoak (Emily Bett Rickards) as she reveals her eagerness to help Ray with his "suicide mission." Although we don't get to see Ray in his Atom suit, Brandon Routh does discuss his burgeoning relationship with Felicity, following their unexpected kiss.

Also in "Nanda Parbat", Malcolm (John Barrowman) is captured by Ra's al Ghul (guest star Matt Nable) and taken to the mythical Tibetan city. Because of his love for Thea (Willa Holland), Oliver (Stephen Amell) considers saving Merlyn. Ray (Brandon Routh) has become obsessed with finishing his Atom suit so he can save the city, but Felicity (Emily Bett Rickards) fears he is heading down the same path as Oliver and tries to pull him out of the lab.

In this exciting new sneak preview, Brandon Routh also mentions that he has no clue Felicity is a part of "Team Arrow," which could lead to some intriguing conflict, given Felicity's past with Oliver. Is there a love triangle brewing in Starling City? Do you think Felicity should be with Ray? Take a look at this preview for "Nanda Parbat" before it airs at 8 PM ET tonight on The CW.
