Following up Doctor Who‘s eternal femme fatale, River Song, with another prize cosplay inspiration, Alex Kingston is joining Arrow as Dinah Lance, Laurel’s mother. According to Zap2It she’s going to be in “at least three episodes this season.”
In comics, both mother and daughter took on the guise of Black Canary, the younger following the elder. It seems a distinct possibility that Kingston will get to indulge in some costumed shenanigans, then – if not in this three episode arc, maybe later.
And pending the continued success of Arrow, maybe Laurel can be seen to take over her mother’s work later. All speculation. All fan bait. All, I think, far from impossible.
