Recently, Agent's of S.H.I.E.L.D. star, Clark Gregg posted this picture to facebook:
The photograph appears to be from Secret Avengers number 10, by Ales Kot and art provided by Michael Walsh, the story revolves around the Secret Avengers deteriorating as a team.
As you can see the pic shows Hawkeye and Phil Coulson with weapons drawn, could this be teasing an appearance by Jeremy Renner on the show?
Or could it be teasing a scene taking place in the fallout coming with Civil War?!
Though it is a possibility that Clark is just messing with his fans, but you never know.
