The midseason finale of "Arrow" is fast approaching, and The CW has released a new clip of the episode's cold open -- which sees Team Arrow learn the potential identity of Sara Lance's killer from earlier in the third season. Plus, there's a nice link-up to "The Flash" midseason finale as Felicity (Emily Bett Rickards) speaks with Caitlin (Danielle Panabaker) over the phone.
"The Climb" sees Oliver Queen prepare for a duel with the League of Assassins leader Ra's al Ghul -- and recent promos show that it will likely be quite a fight. Additionally, a Warner Bros. TV representative confirmed that Ray Palmer's A.T.O.M. suit is set to debut over the course of the episode.
The "Arrow" midseason finale airs Wednesday on The CW.
