In the episode before Agents of SHIELD, there are many foreshadowings, nods, and tie-ins:
Baron Von Strucker and his flunky List are experimenting on Gifted people –the SHIELD agents go into one of his secret bases and rescue Deathlok and the Inhuman Lincoln, but “the twins” are still in custody. List finally escapes to meet up with Baron Strucker in Sokovia,
Coulson tells Jemma to “suit up” — everyone said this in the Avengers film.
Skye’s mother fears their base will be discovered. With Skye’s return to her friends and Lincoln in their custody, this seems likely. Raina meanwhile, seems to want to lead the Inhumans. Cal returns to the base, still unstable, still wanting his daughter returned.
Coulson vows to make up his secret-keeping to May but doesn’t actually do it. She doesn’t completely trust him at this point.
Skye uses her powers, no controlled, in a firefight. She wears her superhero gloves.
Jemma tries to kill Ward, revealing how far she’s gone over to the dark side. Ward meanwhile seems to belive you don’t betray your team and relishes being with them –he seems, like Spike or Angel (or Wesley, Jayne, Willow, and countless others) to want a role among them after betraying them.
Coulson exerts his power — he gives Gonzales the Toolbox but warns him he won’t have it long. He also finds the Staff of Loki for Agent Hill (who cameos), he mentions Fury’s alive (and thus Gonzales wasn’t in the know) and prepares Theta Protocol … and the Avengers.
Bobbi has misgivings about locking up Skye. Mac and Hunter reconcile. The two SHIELD teams are now all stuck in one base, ostensibly working together. Coulson thinks Fury will come soon and settle the chain of command. He also thinks the council is silly.
Raina ends the episode foreseeing men of metal destroying cities and the Staff of Loki playing a part.
