They hinted towards this at SDCC with Patton Oswalt's humorous video clip, now its official. Barbara "Bobbie" Morse aka Mockingbird has been cast and the actress playing her is Adrianne Palicki (Supernatural, G.I. Joe, Friday Night Lights.) This isn't her first foray into the televised adventures of superheroes. She was cast as Wonder Woman in the failed NBC pilot by David E. Kelley back in 2011. She was also in the failed WB pilot for Aquaman, as Nadia an evil type character. Now she'll join the amazing cast of Agents of S.H.I.E.L.D. and play an important Marvel character...important to Hawkeye's love life at least. She'll make her first appearance in the fifth episode and has the chance to return. She joins season 2 guest stars, Kyle MacLachlan, Reed Diamond, Lucy Lawless, and Nick Blood.

What do you guys think of this casting news? Did you stick with Agents of S.H.I.E.L.D. through all of season 1? Are you excited for season 2?

Agents of S.H.I.E.L.D. returns to ABC on September 23rd, 2014 at 9 PM EST and stars Clark Gregg, Ming-Na Wen, Brett Dalton, Chloe Bennet, Iain De Caestecker, and Elizabeth Henstridge.
