Marvel officially published the synopsis for Episode 1 of Season 2 of Marvel's Agents of S.H.I.E.L.D., called "Shadows". The guest star list is long and interesting, including not only the return of Agents Triplett and Koenig and General Talbot, but also a fan favorite of the Captain America-franchise.
"Shadows" - Coulson and his team are now wanted fugitives with limited resources--but that's not stopping them from keeping the world safe from powerful and unseen threats everywhere. However, with new members they hardly know, will S.H.I.E.L.D. ever be trusted again? Watch "Marvel's Agents of S.H.I.E.L.D.," on the ABC Television Network.
Guest starring are B.J. Britt as Agent Antoine Triplett, Nick Blood as Agent Lance Hunter, Adrian Pasdar as Brigadier General Glenn Talbot, Henry Simmons as Alphonso "Mack" Mackenzie, Patton Oswalt as Agent Billy Koenig, Lucy Lawless as Isabelle "Izzy" Hartley, Wilmer Calderon as Idaho, Reed Diamond as Daniel Whitehall, Hayley Atwell as Peggy Carter, Brian Patrick Wade as Carl Creel, Matthew Glave as Roger Browning, Simon Kassianides as Sunil Bakshi, George Stephanopoulos as self, Raquel Gardner as Carla Talbot, Ben Turner Nixon as Hydra Officer, Franco Vega as Military Leader, Rich Ceraulo as Soldier #1, and JB Tadena as Private Tilden.
Considering Hayley Atwell is about to start shoot her own Agent Carter series these very days, having her guest star in Marvel's Agents of S.H.I.E.L.D. makes sense and is also doing the increasing demand for more female representation in the franchise justice. Smart move!
