In the first season of Agents of S.H.I.E.L.D. Coulson (Clark Gregg) and his team took down The Clairvoyant (Bill Paxton). In season 2, it was revealed that Skye is actually Marvel Comics superhero Daisy Johnson aka Quake as the team dealt with betrayal, Hydra, anti-S.H.I.E.L.D. government operatives and the recently discovered Inhumans. In season 3, the conflict with the Inhumans stepped to the forefront as Coulson and Quake assembled their team of Secret Warriors to battle Hive and the remnants of Hydra.
In retrospect, the show has made tremendous strides from season one to season three and has covered a lot of ground in respect to the development of its main characters. Case in point, when season 4 opens, we'll find Quake in a very dark place.
Chloe Bennet tells EW, "
The two people who know she [was ready to succumb to Hive] are both dead, so no one else knows. There must be a moment coming up in the next season where she reveals that. I think she feels like she can’t get close to people because wherever she goes, death follows. That hit home with her, especially this time."
With rumors that the Marvel NOW! Ghost Rider Robbie Reyes (he drives a flaming 1969 Dodge Charger instead of a motorcycle) and his brother Gabe are set to debut, how will Quake's depressed mental state mesh with a Spirit of Vengeance? We should have some answers from Marvel TV next week at SDCC.
Agents of S.H.I.E.L.D. season 4 premieres September 20, 2016, at a new 10 PM time slot on ABC.
