The CW Network has released a plot synopsis for the upcoming Arrow midseason finale "Three Ghosts", airing Wednesday, December 11 at 8 PM ET. While this normally wouldn't be Earth-shattering news deserving of a full story, the rundown teases that Solomon Grundy is likely heading to Starling City. Take a look at the synopsis, then read on for more information.

"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 (Colton Haynes) is captured and tortured by Brother Blood (guest star Kevin Alejandro). John Behring directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Geoff Johns & Ben Sokolowski."

Cyrus Gold was Solomon Grundy's human name before he died and was transformed into the zombie villain from the DC Comics. It isn't known if Graham Shiels has a multi-episode arc lined up for Season 2 or not, or if Gold will eventually become the gruesome Grundy before Season 2 comes to a close.
