Marvel's Agents of S.H.I.E.L.D. S3E5 - "4,722 Hours" Recap

Finally, we begin to learn what happened to Simmons during the six months she spent on the planet. The planet was sun-less and seemingly deserted. Eventually, Simmons had to move from her point of arrival to find water. She's able to find a pool of water but is attacked by an alien inside of it. She is able to fight it off and feed off of its limbs to stay alive. Eventually she meets a man named Will Daniels who initially takes her captive.

Simmons escapes and Daniels chases after her and tends to a leg wound of hers, saying that "it" smells blood. They retreat back into his makeshift living space. Daniels is a stranded astronaut that had travelled through the portal with a team of scientists in 2001 back when the monolith was in NASA's custody. Over time, each member of the team was driven mad by the planet and an evil entity that lives upon it. Everyone died except for Daniels.

Simmons is able to figure out that they can track the stars and alignment of the planet's moons to determine the rate at which the planet rotates. The portal is in a fixed location so they can figure out where it will be and anticipate the next time that it opens. Just before the last of their power dies, they are able to learn that the portal will open in eighteen days and the location is somewhere quite dangerous. Unfortunately, they're unable to get to the portal in time. They try to shoot a message in a bottle into the portal that contains all the information they had gathered so that Fitz would know how to get them out but they just barely miss it.

Simmons loses hope of ever getting home but finds comfort with Daniels and falls in love with him. Some time later, they see a flare sent through the portal by Fitz. While Daniels distracted the evil entity, Simmons was able to make it to the portal and return to Earth. This brings up back to the present, where Simmons has finished explaining to Fitz that now she needs to reopen the portal so she can rescue Daniels. Fitz agrees to help while Daniels is shown to be still alive on the planet.
