Arrow is adding a familiar face to genre fans for Season 2, as Summer Glau joins the hit CW series in a new recurring role. THR reports that Glau, known for series like Firefly and Terminator: The Sarah Connor Chronicles, will play Isabel Rochev, introduced as the “vp acquisitions at Stellmoor International, a company looking to take over Queen Consolidated.”

Summer Glau will play DC's Isabel Rochev.

Isabel is described as "enigmatically beautiful" and "dangerous.” Fans of the Green Arrow comic books may recall Isabel, who often wore a mask, introduced in Green Arrow in 2010, where she claimed to have some pretty major connections to Oliver’s father, Robert Queen.Glau will make her debut in the Arrow: Season 2 premiere. Her casting is somewhat amusing, given many fans have speculated she would inevitably be cast by frequent collaborator Joss Whedon in his new Marvel’s Agents of S.H.I.E.L.D. series – but it looks like DC got her first!
