Spoilers ahead for Episode 7 of Agents of S.H.I.E.L.D. Season 7, called “The Totally Excellent Adventures of Mack and The D.”
Original Coulson died and then was T.A.H.I.T.I.-ed back to life, then he died again from his illness, then he kinda sorta came back as Sarge, then he came back as an LMD, and now, in the 1980s-tastic “The Totally Excellent Adventures of Mack and The D,” Coulson came back again despite his body being blown up in the previous episode.
Agents of S.H.I.E.L.D. has developed a habit of killing off versions of Phil Coulson over the years, even if his first death technically happened in The Avengers.
And this needs to be the last death-and-resurrection for Coulson for the rest of the series.
