On the surface, the show doesn't seem like it would be that action packed, but as the show finishes up its second season, many fans are very excited at all of the new action in store.

In the last episode, we find out that Skye is actually Daisy Johnson also known as Quake. She has the powers to make earthquakes and she is also a psychic shield. We also find that The Doctor is really Mister Hyde. In this episode, we see that everyone who comes out of the hidden city will be forever changed. Fans learned many new identities in this episode and saw just what powers some of the Inhuman now possess.

HYDRA attempted to kidnap Raina and when she is saved, she reveals a great secret about the hidden city to Skye. Raina told Skye that only the "worthy ones" were able to enter the hidden city. In this episode, we see Skye finally meeting her father and that is when viewers learn of their superpowers.
