Absolutely agreed. He's a complete fucking weirdo and I love him for that. My personal Equius headcanon is that he HAS actually succeeded at shooting a bow and arrow without breaking it, once, with perfect accuracy, by some miracle.
He felt so viscerally uncomfortable with this outcome for reasons he could not verbalize that he had to take a cold shower while Aurthour lingered concernedly nearby with a glass of milk. He has never mentioned or even thought about it since.
