The Inventor is a bit of a mystery. No-one knows how old he is, but he looks like he’s in his early teens. He’s not aged at all since Alice has known him (25 years). He tells people that it’s down to his clean-living, but Alice suspects it’s more to do with some kind of quantum mirror in his attic.
The Inventor knows things. He knows how to make things work. He knows how to build things that haven’t been invented yet.
He communes with tech.
When Alice and the Dragon have thrown their hands in the air in despair at an impossible obstacle, the Inventor looks at it, clears his throat and then says ‘Have you tried this? Seems obvious to me’.
‘Smartalec’ doesn’t even begin to describe him.
