Sneak Peek new images, plus footage from Part 2 of The CW's "Arrow" and "The Flash" crossover episode "The Brave and The Bold", from a story by Greg Berlanti, Andrew Kreisberg, teleplay by Marc Guggenheim, Grainne Godfree Schwartz and directed by Jesse Warn, airing December 3, 2014:
"...'Oliver' (Stephen Amell), 'Arsenal' (Colton Haynes) and 'Diggle' (David Ramsey) track down the location of a boomerang-wielding killer named 'Digger Harkness' (Nick Taraby) but are surprised when they come face to face with an 'A.R.G.U.S.' team.
"Diggle asks 'Lyla' (Audrey Marie Anderson) why A.R.G.U.S. is involved but she defers until Harkness attacks the building, killing several agents and targeting Lyla.
"The 'Arrow' joins the fight and gets help from an old friend – 'The Flash' (Grant Gustin). Harkness manages to get away and Oliver teams up with Barry again to find him before he can get to Lyla.
