When you watch Marvel's Agents of S.H.I.E.L.D. Season 5 Episode 21, you're thrust right back into the action, with Coulson and May being held captive by the Remorath and Daisy in the hands of Taryan, the father of the cruel Kasius they encountered in the future as the lord and master of the remnants of humanity. Talbot's insanity grips ever more tightly on his mind and his craving for gravitonium increases. Even though he wants to save the world, he only sees enemies in his friends, and there's little any of them to do to stop him. Fitz and Simmons, meanwhile, continue their research into a possible cure to save Coulson's life, and Mack gives them further directions to figure out something to potentially handle Talbot, even if it kills their former friend, in order to save the world. Deke and Davis, meanwhile, are left on the Zephyr and must hold their own and do something to help their colleagues on the alien ship. Is there anything that the Agents can do at this point to escape their various predicaments? What can they do about Talbot? Find out what happens when you watch Marvel's Agents of S.H.I.E.L.D. Season 5 Episode 21 online!
