This week's threat is "The Real Deal"! Last week's explosion caused the monoliths to open a strange rift in the Lighthouse, and it's letting another dimension leak into our world and manifesting everyone's fears into reality. Fitz thinks he can hold it back, but it may involve someone sacrificing themselves to do it. Of course all the agents volunteer, but Coulson knows it's his duty to play the hero. But when he passes out, the secret of his failing health is revealed to everyone. While they're understandably upset, they know there's still a job to do. While avoiding manifestations of past threats like LMD's, Lash, and Kree, the team works to save the world, while their new friend Deke goes shopping for a special occasion they'll celebrate IF they survive the latest disaster. Jay and Josh are joined by special guest agents Joe, Lou, and Tim as they celebrate the centennial episode of Agents of S.H.I.E.L.D.: Case Files.
