This week's episode of Arrow was pretty crazy, with viewers being introduced to Barry Allen, a CSI investigator with a dark past who's a super-strong criminal who just so happens to be working for Brother Blood. But that was merely the first part of the midseason finale, which concludes next week with "Three Ghosts."
In anticipation, The CW has released two photos, a synopsis and the trailer for the episode.
Here's the episode's official synopsis from CW:
After a fight with Cyrus Gold AKA the Acolyte (guest star Graham Shiels), Oliver is drugged and left for dead. Determined to cure him, Felicity makes a risky decision. The cure causes Oliver to hallucinate, and what he sees forces him to confront his past. Meanwhile, Barry (guest star Grant Gustin) continues to help Felicity, and their connection grows stronger. The Arrow asks Lance to look into Gold, but when the stakeout on Gold goes bad, someone is killed. Roy is captured and tortured by Brother Blood (guest star Kevin Alejandro).
The Arrow midseason finale airs Wednesday at 8 p.m. ET/PT on The CW.
