Gerald[2] Jones "Jelo Elducal" Bartholomew Edmarkson[3] is a character in In a Locked Room, The Great Crossover Competition, and The Shenanigang. He is one of the mascots of IaLR. He is roleplayed by JeloElducal.

Gerald is the founder and one of the leaders of the Locked Room Gang, a group of heroes who stop villains from taking over the multiverse, especially Galaximus. While the leader of the Gang, Gerald doesn't actually lead the Gang.

As revealed in Isolation Point, "Jelo" is actually a nickname, and his real first name is Gerald. His real last name is revealed in the story "Time Stop" as "Edmarkson". In addition, "Elducal" is revealed to also be part of his nickname.


Pre-Locked Rooms

Jelo was born in Echo Creek, Los Angeles on Dec. 19, 1993. When he was at kindergarten, he met Rosewell, and they became friends. They entered the same high school and college. When he was 12 he joined a camp named Camp Sherlock. At one time, he went up the camp bus and looked at the Comet Observatory with a telescope, but quickly went back inside due to a traffic sign about to hit him.

Jelo met a handful of Gang members before they joined the Gang. Jelo knows everyone in Echo Creek for no reason, but he met Star and Marco as random people walking by; Mario, Luigi, Peach and Daisy in a videogame convention (Peach and Daisy are also his neighbors for some reason); Phineas, Ferb and Milo also as random people walking by during his trips from Danville, and more.

When he was 23, he heard of the Locked Room Challenge while he was camping. Jelo said, "That's impossible! A challenge full of cartoon universes? Well, I'd try it." Jelo went near the entrance of the Locked Rooms. However, a Wizard Zombie jumped out of nowhere and started shooting spells at the campers, turning a Sweet Potato into a Lighthouse Flower. Jelo then ran around like crazy, and was hit by the zombie's spell. The portal then suddenly activated when Jelo neared, and sucked Jelo in.

Post-Locked Rooms

After the gang escapes the Locked Rooms for the last time, Jelo was worrisome about the friends and family of "the missing ones". He decides to brush it off and enjoy the town celebration, but he felt really guilty, thinking about how would they react once they find out their loved ones ended up missing. He still stayed optimistic, however.

After a bunch of apologies, Jelo returns to his normal, suburban lifestyle. He still hangs out with the Gang, though.


In his first appearance in the Hot Room, he was the letters "Jelo" in an orange background, a result of a curse. Some time later in the Cold Room, Jelo became a Papa Louie-style person. He then became a cartoonish-style person. He has messy hair, a brown jacket, brown shoes, a brown belt, blue pants and a light blue shirt. In his Flipline look, he had an aqua and black shirt, which he still keeps.

His current look now brings back his glasses. He now has brown sneakers, his pants now have more pockets and added seams, and he now wears a light blue polo shirt with a pocket. His watch was removed.

His real look is actually the cartoonish look. The Papa Louie one is actually a stage of the rehumanization, and the letters in an orange background are just a mere curse, which weared off after Season 1b.


Jelo cares to help his friends through rooms. He is intelligent, usually easy going, witty, courageous and calm. He never gives up when doing a hard task, and likes to help other people around him.

Jelo is friendly to people. He is supportive of others, is organized, and likes studying. He also likes hanging out with friends, and also likes playing games. He also likes watching videos, and listening to music, usually those from the 70s-90s. Jelo can sometimes be a bit scatterbrained and clueless, however.

Like all characters, Jelo also knows how to break the 4th wall.

Milo Murphy

"He's persistent, optimistic and the human equivalent of Friday the 13 turned up to 11."
— Gerald, talking about Milo

Jelo is friends with Milo. Jelo is trying to survive the disasters caused by Murphy's Law, and has always managed to do so successfully everytime.

Everyone else

Jelo is friendly to the whole gang, mean to bad guys, and neutral to strangers.



  • In the Season 1 finale, Jelo is unaffected, because he has no powers.
