Wattson is Professor Toby Birch’s father and Brendan’s grandfather! He tried to get his son interested in engineering like himself, but Toby always preferred getting out and studying nature instead – not that Wattson minds! He’s happy when his family’s happy after all. He and Brendan get along really well. Wattson always liked to show Brendan all his latest projects as he worked on them, which fascinated the boy, even if he didn’t really get any of it (and still doesn’t as an adult. He takes more after his father in interests.)
