Which Two Avengers Will Appear On 'Agents Of SHIELD'? Jed & Joss Whedon Drop Hints

Last seen scribbling alien gibberish into the walls of the Playground as his team slept, Coulson (Clark Gregg) appeared to be following in Agent Garrett's (Bill Paxton) crazy footsteps.

"He was talking about all the things that were happening to the people they were using on it and why he suggested they can the whole thing - and looked pretty shaken while he was saying it. So I've got to suspect that some of the stuff he saw and some of those patients have some version of the stuff that's going to happen to him."
