Mockingbird In Agents of S.H.I.E.L.D. Season 2

The Executive Producers of "Marvel's Agents of S.H.I.E.L.D." have sent a Morse code to say they've found their Mockingbird!

Adrianne Palicki will appear as Bobbi Morse, a.k.a. Mockingbird, in the second season of "Marvel's Agents of S.H.I.E.L.D."--but whether she'll play friend or foe to Coulson and his team, we can't say. Known for her work in "Friday Night Lights" and "G.I. Joe: Retaliation," Palicki most recently appeared in several episodes of "About a Boy."

We all remember Palicki was in that failed Wonder Woman TV series, right?  Anyway, below is (I believe) a current incarnation of Agent Barbara "Bobbi" Morse,
