Ming-Na Wen is full of energy in her amazing panel from Fan Expo Dallas 2015 on May 30, 2015!!! If you've seen season 1 of S.H.I.E.L.D. you should be pretty good to avoid spoilers. They talk about the season 2 episode explaining how Agent Melinda May became known as the Calvary, but she doesn't go into too much detail on that episode. Ming-Na demonstrates an awesome kick, talks about S.H.I.E.L.D, Mulan, and more!
