Even the agents who have encountered things like LMDs may not be inclined to assume that this new guy who looks just like their friend who died is a baddie, especially if they’re deeply missing Coulson 1.0.
The trailer seemed to reveal a more sinister Coulson who didn’t have the S.H.I.E.L.D. connections and humor that made him so endearing, and Clark Gregg told CinemaBlend’s TV Editor Nick Venable that the new Coulson will look “an awful lot like Phil Coulson to these people,” but “may be a little disturbing.”
