Tonight is the big night for the kick off of Marvel’s Agents of S.H.I.E.L.D. Season 3. We are here to get you ready for tonight’s episode by sharing with you everything we know so far leading into the start of the season. When we last left our S.H.I.E.L.D. friends, the Terrigen crystals had been dumped into the ocean opening the door for the big reveal of more Inhumans. Not to mention Agent Simmons was swallowed up by the big black alien entity and Director Coulson had his arm chopped off. What will we see tonight? Check out all the clips leading into the season premier below, and share your thoughts AFTER THE JUMP!
