The CW's 'Arrow' will have plenty of leftover conflicts to resolve when Helena Bertinelli (Jessica De Gouw) comes back to Starling City March 20 for "The Huntress Returns," but what of the "Unfinished Business" with The Count ('Fringe's' Seth Gabel) and his "Vertigo," who was last seen being dragged off to a psych ward? 'Arrow's' deadliest threat will soon return, so find out what brings "Vertigo" back into play in an upcoming episode inside!

Life never gets any easier for the Starling City vigilante, but that goes doubly so when displaced villain The Count comes back into the 'Arrow' world. After the character's initial appearance, the DC Comics-adapted Vertigo will return for April 3 episode "Unfinished Business," as revealed by The CW's most recent press release:

ARROW - "Unfinished Business"

GUEST STAR SETH GABLE ("FRINGE") RETURNS AS THE COUNT - When a young woman meets a violent death after partying at Verdant, Detective Lance (Paul Blackthorne) and his new partner, Detective Hilton (guest star Roger Cross) inform Oliver (Stephen Amell) and Tommy (Colin Donnell) that she was on the drug Vertigo. Oliver immediately pays a visit to the mental institution where The Count (guest star Gabel) is locked up, but finds he is in no condition to deal drugs.

However, when The Count escapes and Starling City is flooded with even more Vertigo-related violence, Oliver and Diggle (David Ramsey) make it their mission to track him down. After Detective Lance uncovers incriminating evidence against him, Tommy goes to great lengths to clear his name, and the fallout from his actions leads Tommy down a new, unexpected path. In a flashback to the island, Oliver recalls the lessons he learned from Slade (guest star Manu Bennett) and Shado (guest star Celina Jade)

The Count certainly seemed to become even more unhinged after a dose of his own medicine, but will Oliver Queen be able to bring him back down to Earth? And how will Tommy cope with being so intertwined with the vigilante, now revealed as his best friend?
