SETH GABEL (“FRINGE”) GUEST STARS WHILE THEA FACES PRISON TIME — Thea is in trouble with the police after she gets caught using a drug called “Vertigo.” Oliver thinks the only way to keep her out of jail is to find the dealer, a man who goes by the name of “The Count” (guest star Seth Gabel). Oliver turns to McKenna Hall (guest star Janina Gavankar), an old flame and current Vice cop, for help. Meanwhile, Laurel steps in to defend Thea, and Felicity (guest star Emily Bett Rickards) gives Oliver some disturbing news about Moira. David Ramsey, Colin Donnell and Paul Blackthorne also star. Wendey Stanzler directed the episode written by Wendy Mericle & Ben Sokolowski.
