Not that his was a really nice guy ever. But the second part is close to true in some sence.

This guess is exact! I'm sure I've never told about this aspect in the internet. How have you guessed?
He's really good in scientific fields and he loves the sound and the smell of rain.
Nah. He doesn't really know much science, except that aspects, which are related to his own body modifications, weapons and other devices, which he uses, i.e., mostly applied knowledge. Also he has some taste in literature.
About the rain... honestly, I've never thought how would he like it
