"Possibly Echo or Kyle, since the restaurant Echo works at is just down the street and Kyle lives in a studio apartment upstairs."<br/><br/>EDIT: "Actually this might be a good idea."<br/><br/>"Okay, KC lives in an apartment with Kana, his nurse, and is haunted by the ghost of a girl named Harumi (who he's known since they were kids). CJ and Syn live in one of the adjacent apartments (if you look up you can see the layout of the two-bedroom apartments in KC's as yet unnamed building). Kyle lives upstairs in a studio apartment."<br/><br/>"Echo lives in another apartment building not too far away and works at 'The Cafe', which is down the street from KC's building. Jude, Prudence, and Willow all live together in their moving house which currently has no specific location, but is presumably somewhere in a 15 mile radius of KC's building."
