The actress will play the recurring role of Dinah Lance , Laurel’s (Katie Cassidy) mom and Detective Quentin’s (Paul Blackthorne) ex-wife.
Dinah will first return to Starling City in the latter half of this season, to fix things with her family that she abandoned years earlier following the death of her daughter aboard Oliver Queen’s yacht.
