According to Moviezine, the actress is the last pic is
Pascale Armand. She doesn't have a lot of film or tv work under her belt, but she's apparently a part of the
Agents Of S.H.I.E.L.D cast..unless it's just for this episode. Who could she be playing? Who could those red mask wearing gents be? Be sure to leave your thoughts in the usual place.
UPDATE: A user on the
Bleeding Cool forums may just have cracked this one:
Could these guys be Flag Smasher's terrorist army, "Ultimatum"?
