This time it is True Blood's Janina Gavankar. She will be playing "McKenna Hall” in a multi-episode arc.
McKenna is a Starling City PD vice cop, but she knew Oliver Queen back in his pre-island bad boy days. When a new drug called Vertigo — dealt by a dealer character played by Fringe actor Seth Gabel — starts wrecking havoc, their paths will cross in more ways than one.
