Marvel's [Agents of S.H.I.E.L.D.](tag:722469) season 3 is going great. However, the big question is: where was Simmons? It is known that she was on an alien planet and the last episode we got more information. Will the astronaut Simmons meets on the planet says that the planet has moods and believes that it's punishing them. The planet also has planet-like creatures, water, sandstorms and no sun. Even though this information doesn't confirm anything it does make a certain theory come to mind. Could the planet be Ego, The Living Planet?
Ego The Living Planet
Ego The Living Planet as the name suggests is a sentient planet initially introduced in the Thor comics. Ego lives in the black galaxy, black as in no sun. Granted I would like to believe that if the planet was Ego that it doesn't have a face/talks like it does in the comics because there has to be some realism somewhere. Like what Will said in the episode he believes the planet has moods, a personality which would be a extremely clever way to introduce a character (technically) which was never going to be used as a villain in a Thor movie and found away to use him intelligently and organically if it is Ego. Anyway, if it is or isn't Ego, it does expand the cosmic universe and this planet could potentially be shown in [Guardians of the Galaxy Vol. 2](tag:1081113) or Captain Marvel as a easter egg.
