It seems like the obvious thing though to have him be the evil thing.

Spoiler!

Close, Will was real, after Gemma left we had the scene with Will dropping his gun, I expect that he was killed as Gemma went home.

This thing doesn't imitate, it seems to be a parasite that can re-animate dead bodies. Will's leg was rotted to the bone when Fitz took off his bandage.

Loved Coulson killing Ward like he did
