Marvel Agents of S.H.I.E.L.D. continues to fortify its ranks.
TVLine has learned exclusively that the ABC drama has promoted Henry Simmons to series regular status for Season 3 — on the heels of doing same for series newcomer Luke Mitchell.
Simmons made his debut as Alphonso “Mack” Mackenzie in the Season 2 premiere, as part of newly installed Director Coulson’s expanded team. He went on to appear in every episode thereafter, though there was a moment just before the Season 2 finale when it appeared Mack had called it quits, saying he was unable to work for a man who was so alien-friendly.
