The second part of The CW's "Arrow"/"The Flash" crossover hasn't even aired yet, but the network has already provided a glimpse of next week's midseason finale, in the form of 28 new images from the episode. Titled "The Climb," the episode (directed by Thor Freudenthal and written by Jake Coburn & Keto Shimizu) features a face-to-face meeting between Oliver Queen (Stephen Amell) and Ra's al Ghul (Matt Nable) -- and based on these photos, it looks like it involves snow, swords and no shirts (and as comic book fans know, Ra's al Ghul is no stranger to shirtless sword fights). The images also feature Katrina Law, returning to "Arrow" as Ra's daughter, Nyssa al Ghul.

"The Climb," the midseason finale of "Arrow" season three, airs 8 p.m. Wednesday, Dec. 10 on The CW. Here's the official episode synopsis:

RA'S AL GHUL GIVES OLIVER AN ULTIMATUM; DINAH LANCE PAYS LAUREL A VISIT - Nyssa (guest star Katrina Law) returns to Starling City and tells Oliver (Stephen Amell) that her father, Ra's al Ghul (guest star Matt Nable) has given Oliver 48 hours to find Sara's killer or the League of Assassins will start killing the citizens of Starling City. Laurel (Katie Cassidy) is stunned when her father (Paul Blackthorne) delivers a very special Christmas gift - her mother, Dinah (guest star Alex Kingston). Meanwhile, Ray (Brandon Routh) tries to make amends with Felicity (Emily Bett Rickards) and Oliver sets a meeting with Ra's al Ghul.
