Doctor Who’s Alex Kingston has been cast in The CW’s Arrow as Laurel’s absentee mother and Detective Quentin’s ex-wife Dinah. Her story arc will center around her return to Starling City to patch things up with the family she left behind after the death of her daughter on Oliver Queen’s ship.
Speaking of ships, this is sure to inspire some interesting cross-over “ship” fanfic on sites like Tumblr, which is known to be a hub for fans that are preoccupied with rather uncommon ”romantic” entanglements. I can see it now: Dr.Arrow: The Many Identities of River Song, complete with theories about how the time lady made her way to another completely different universe. Although nothing tops Superwholock.
