Will the two gifted scientists Leo Fitz and Jemma Simmons discover who is HYDRA's Inhuman on "Marvel's Agents of S.H.I.E.L.D.?"

In the eighth episode of the Marvel Television and ABC Network-produced series, "Many Heads, One Tale," Gideon Malick (Powers Boothe) told Grant Ward (Brett Dalton) how they could destroy S.H.I.E.L.D. Malick shared with Ward his knowledge of a powerful Inhuman who was "destined to rule" the humans and the whole world, Comic Book noted.

However, this same Inhuman was transported into another dimension -- just like what happened to Simmons in the second season's finale -- because he was banished. The show revealed that HYDRA's main objective for so many years now was to bring back the Inhuman.

Comic Vine noted that with the creature's return to Earth, he and Ward will also reign the world with it. They will be greater than ever as they have the Inhuman working with them to achieve their goals.

It was not actually explicitly revealed if the other side where the monolith transported Simmons was the same planet where the Inhuman had been staying, but it seemed most likely the case.

If it is, then it is highly probable that Simmons (Elizabeth Henstridge) and Fitz (Iain De Caestecker) will be facing HYDRA's chosen ruler and monster. In the "4,722 Hours" episode, Simmon's experiences in the other world were shown.

The viewers saw all the hardship she went through from drinking water from a small pond to eating the tentacles of an alien creature from the pond, Comic Book informed.

Simmons also met a NASA astronaut, Will (Dillon Casey), who arrived in the planet via a space mission in 2001. Will fed her and even gave her hope to carry on with her life despite very bleak chances of going back to Earth or be found alive. Her strong bond with Will in those trying times on the blue planet made her commit herself to a rescue mission to save him. She is willing to return to the portal to get him back, like what Fitz did to her.

Fitz agreed to help her in her mission concerning Will, despite knowing what happened between Simmons and Will. With the duo's genius working together, they could find a way to go back in the blue planet. However, if the HYDRA's monster in place, the lab partners Fitz and Simmons will be in danger.

Who is Hydra's Inhuman? Could it be the creature whom Will was trying to battle so that Simmons could go back?
