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.
