Last week’s Season 6 premiere returned two actors whose characters’ fates were less than optimistic – Coulson had gone off to die, and Fitz was stranded in suspended animation in a far-flung corner of the universe. But though the actors returned, they were barely recognizable: Clark Gregg was playing not the affable Coulson, but a ruthless, murderous lookalike – and Fitz, played by Iain de Caesteker, concluded the episode by returning as Fitz, but he, too, was a much fiercer version of himself.
