oh my god yes!!!! that's such a cute scenario 🥹 your message immediately reminded me of this art by Cam (https://x.com/tanukified/status/1864760871085338730?t=yu1VHradd1UCU5FlQtzDFg&s=19) and also this super sweet fic where lyney and wrio get some bonding time in on a rare Fontaine snow day (https://archiveofourown.org/works/60199444) ❤️

as for my own input, i love the thought of wrio not really knowing what to do with himself when faced with such juvenile ways of having fun bc he's never really had the opportunity to indulge those when he was young. he's had to grow up so quickly and had to say goodbye to his innocence at such a young age :'( lyney at least has enough whimsy left in him to show wrio how to build snowmen and make snow angels and have snowball fights. wrio doesn't really see the point in doing the first two, but he gets the hang of snowball fights really quickly and gets much more into it than lyney ever imagined. they start out fashioning a dodgeball like playing field in the Fontainian countryside where there's lots of rocks and trees and bushes to hide behind, and they do some strategic battling with snowballs as ammo and not crossing the border between their territories. but it doesn't take long before they're chasing each other through the woods and using dirty tricks to hit eachother. by the time they're done, they're completely out of breath, covered in snow from head to toe and sweating rivers underneath their warm clothes, so they quickly hurry back inside to soak in a steaming bath and gulp down the hot chocolate lyney has been making for his siblings since he was young. ❤️
