Hello, Sweetie! Doctor Who fans will be thrilled to hear that Alex Kingston has been cast as Laurel’s mother on The CW’s Arrow. If you haven’t been watching it’s a great show and already home to another Who alum, John Barrowman. Captain Jack never did meet River Song, did he? I’m sure they would have gotten along famously.

Here’s the scoop from EW.

Former ER series regular Alex Kingston is joining The CW’s breakout superhero drama Arrow in a recurring guest star role. The British actress will play Dinah Lance — Laurel’s (Katie Cassidy) mom and Detective Quentin’s (Paul Blackthorne) ex-wife. Later this season Dinah will return to Starling City to make amends with her family that she abandoned years earlier following the tragic death of her daughter aboard Oliver Queen’s (Stephen Amell) yacht.

Arrow, starring Stephen Amell, Colin Donnell, Katie Cassidy, David Ramsey, Willa Holland, Susanna Thompson, Paul Blackthorne, and John Barrowman, airs Wednesdays at 8/7c on The CW.
