We're hardcore counting on a few Philinda flashbacks in the Agents of S.H.I.E.L.D. Season 6 premiere to help us bid adieu to Coulson, but that's not the only opportunity we'll have to see him in action -- there's a whole world of Marvel movies out there, after all! Most importantly, the Avengers saga is coming to an end with Avengers: Endgame, and it would be fitting if Coulson made an appearance in the film given that his "death" was what formed the Avengers in the first place.
While catching up with the S.H.I.E.L.D. cast at the Television Critics Association winter press tour, we couldn't resist asking Gregg about future big-screen appearances by Coulson -- more specifically, whether we should keep our eyes peeled for one last showing from him when Avengers: Endgame hits theaters on April 26.
Like all other actors in the Marvel family, Gregg was tight lipped (ever-aware that Marvel snipers can and will take you out at a moment's notice for spoiler-related offenses), but he didn't rule out the possibility. "In the world of Marvel anything's possible," Gregg told TV Guide of a potential cameo.
If he were to make an appearance, we'd bet on it being a post-credits scene, but there is also the possibility of a flashback. A popular theory about Avengers: Endgame is that the team will play around with time in order to defeat Thanos, and with time traveling usually come visits from dearly departed characters.
We guess time will tell whether Coulson will make a cameo in the franchise's final installment!
Marvel's Agents of S.H.I.E.L.D. returns Friday, May 10 on ABC.
