Silly is currently dating Grian. The two had their first date when Mr Chupa sent them along with some others to retrieve a special book in the school basement, resulting her, Grian, Sam, Jorje, Taurtis and Jamberite in being transferred to a different timeline, in which Grian and Invader were in an "open relationship." It is made clear that Silly does not approve of Grian being Invader's boyfriend, but she appears to tolerate it. There are often times when Silly takes the role of the "submissive" person in their relationship, following Grian's orders and commands.
