In Marvel's Agents of S.H.I.E.L.D. two-hour season 3 finale, (episode 21 "Absolution" and episode 22 "Ascension," airing Tuesday, May 17 9|8c), it's a showdown a season in the making as S.H.I.E.L.D. takes on Hive (Brett Dalton), and when his master plan is finally revealed, the team must spring into action. In the sneak peeks below, Yo-Yo (Natalie Cordova-Buckley) urges Mack (Henry Simmons) to speed up the installation of a contraption that will hopefully trap Hive. While Daisy (Chloe Bennet) and Coulson (Clark Gregg) are locked in a containment module on the alien planet Maveth. Daisy tries to hack the controls to fly them back to Earth, but Coulson tells her that this is Earth. Who will live, and who will die?
