I had a thought not too long ago while watching reruns of KND on CN.
What if, after Nigel left, Wally was so upset that he just threw himself into his studies to try to block out the pain of losing one of his best friends? So like, ANY time he started thinking about Nigel [never coming back…], and started to get upset, he’d just crack open a book to fill up his brain & block out the pain. Because he didn’t WANT to think about it. And over time, retaining that knowledge built up to him being super smart? (How else could a guy go from thinking 2+2=Pizza to being Harvard material)?
That, and he REALLY looked up to Numbuh 1 throughout the show….a LOT.
