"When we last saw Director Coulson and his team, they were at war with Hydra. That hasn't changed. In "Aftershocks," they must continue to deal with the consequences of that battle. And Hydra makes a move that might mean there's a traitor in SHIELD. Again. But, there is a change the team has to face. Skye was exposed to and affected by Terrigen Mist in the midseason finale. She's learning who she truly is, and her Inhuman abilities are bound to shake up SHIELD."
So Skye apparently has some kind of telekinetic powers, the bad girl turned into a prickly pear, and it looks like there are a couple of more spies inside Shield. Back to the same old jumping everywhere Shield. I miss Agent Carter already.
