@Black Bart is clearly watching South Park. In search for another clue.
Perspicacious... but no.
Nice thinking, but not the right answer.8514.8 km is the exact distance from Tinley Park, IL, USA to Plovdiv, Bulgaria, so this is clearly an indirect reference to @MrKnickerbocker and @Magnus! Since they’re both fans of the Somewhere In Time era, and the other clues reference unhealthy obsession, I’m going to go with “That Girl”.
