Having been born and raised in a warm climate, I imagine encountering snow for the first time (real, actual snow, not magically-induced frozen water shards being vomited out of an ice volcano) is probably going to be novel and amazing for about ten minutes before the cold starts seeping into his bones, and then the general mood becomes ‘what is this blazing white hellscape’
Layers help a lot. Even if his cheeks still sting and his nose still runs and no amount of layering will keep your toes from going numb when you’re out walking long enough.
Once he discovers sledding, though, he flips like a switch. Cold? What cold? Too fast to be cold. One more ride! Warmth is for the weak.
