SPOILERS AHEAD FOR "Marvel's Agents of S.H.I.E.L.D." SEASONS ONE & TWO
One of the big mysteries left hanging at the end of the first season of "Marvel's Agents of S.H.I.E.L.D." is that of the blue alien corpse discovered halfway through. Said body was the source of a serum which helped bring Agent Phil Coulson back to life.
The show never identified what race the alien was, but one possible answer has now been revealed - it could well be a Kree, a race Marvel introduced into its cinematic universe through Lee Pace's Ronan the Accuser in the recently released "Guardians of the Galaxy".
A behind-the-scenes set video of filming on the show's second season has been posted. The scene features Coulson and Skye, along with a muscular man with an arm turning the same blue/grey as the being Coulson found last season.
The source who posted the video also said: "For almost the entire day they were filming this little sequence that happens out here, which I found out, that guy sitting on a park bench is a Kree or is part Kree... and someone is trying to kill him."
