Combeferre for the weird headcanons!
What they smell like: I don’t want to say ‘subtle but warm and envelopping cologne, the kind that the perfect date would wear to take you out’ because this is the least specific thing but, yeah.
How they sleep (sleeping position, schedule, etc): not very well at all; with a night light, windows cracked open when reasonnable to do so, otherwise definitely some gentle music playing.
What music they enjoy: instrumental, to help focus, and world music.
How much time they spend getting ready every morning: not much! shower, shave, get dresses. he can usually be out the door in under an hour, usually around half.
Their favorite thing to collect: bOOKS. and shoes. bookmarks, but he never uses them.
Left or right-handed: Right-handed.
Religion (if any): Agnostic - he’s open to a lot of things.
Favorite sport: Soccer, definitely a soccer guy.
Favorite touristy thing to do when traveling (museums, local food, sightseeing, etc): EVERYTHING. He loves going to see local theater, but also museums, obviously, and sightseeing.
Favorite kind of weather: Sunny, warm, the best weather for long walks, but he also loves these dark few minutes before a thunderstorm.
A weird/obscure fear they have: He still has nightmares about getting to class and realising he forgot to put on pants.
The carnival/arcade game they always win without fail: he can play pinball forever and probably holds a couple of records at the pub ahah.
