Jessica Locke is a minor turned major character in the MarbleHornets ARG. Her first appearance is in Entry #27 as a side cameo and becomes a major plot point in Entry #28. Jessica is the occupant of the room right next to Jay in the hotel after he wakes up from his seven month gap in his memory. She doesn't know Jay of the present due to the Operator's influence and her relation with Jay is told entirely through camera footage. Jessica seems to be privately bothered by her memory loss and insomnia. In Entry #87, it is revealed that Jessica somehow survived her encounter with Alex in Entry #76. The details behind this are unknown, but it is stated that she has since begun taking medication much like Tim. She is unaware of Jay's death, and Tim lies about him moving, possibly to protect her.
