Scooby-Doo

Tyson’s nephew, James, used to love Scooby-Doo and all the mysteries. When Tyson would babysit him, there would be a dozen Scooby-Doo DVDs tucked in his rucksack to watch on the journey down and whilst cuddled up, barely awake in his uncle’s arms on an evening.

Though those DVDs were steadily rotated through, there were three that showed up far more than the others: The 13 Ghosts of Scooby-Doo!, Scooby-Doo and the Ghoul School, & Scooby-Doo! and the Witch’s Ghost.

Ghosts

As mentioned here, Tyson doesn’t believe that ghosts exist, but he believes that they could exist and doesn’t discredit the idea. Sometimes fortunately and sometimes very unfortunately for him, his main!universe isn’t quite the real world: with the Moriarty Mirrors, Draco, advanced nanobots, and more existing.

Bobby can see ghosts and is able to seek them out. He will go out of his way to find ghosts, even taking Tyson miles off course. Though Tyson has his dogs trained to an incredible level, the former Lieutenant largely allows his dogs to do as they wish unless given a direct instruction. That training means he can trust them enough to allow such a loose metaphorical leash.

Unless Tyson is trying to get somewhere specific, when Bobby starts leading him and Lily off to the left on their morning walk, Tyson shrugs and follows the course Bobby would like the walk. He doesn’t understand what exactly is catching his Dalmatian’s interest, but he enjoys the opportunity to take a new route and see different areas of London when it happens.
