Rory has a disorder in the autism spectrum, possibly Asperger Syndrome, given his bullies nicknamed him "Ass-Burger". The condition also gives him savantism of sorts, enabling him to restore chess boards to their previous condition before the pieces were knocked down by said bullies. Rory is an avid video gamer, liking shooters in particular because they remind him of his father (even if Quinn had forbidden him from playing that genre).
In October 2018, Rory received a package originally intended for Quinn's PO box. Inside were a mask and a wristband worn by an alien creature, with Rory removing a device that worked as a portable computer from the latter and managing to decode how it worked.
He was kidnapped by the Upgrade Predator because of his autism, which the predator believes is a useful trait, which is confirmed by Casey, as she says that Asperger is the next stage in human evolution. Rory is freed by his father and The Loonies, who also manage to kill the Upgrade Predator with the help of Rory.
Since then he has been helping his father in the Stargazer Project. He proves to be invaluable in this work, due to his ability to understand the Predator language.
