Congratulations on the update, and Caspar is adorable. His condo is so cute!
Oof those are very hard questions!!! The only answer I have for 1) are kind of stereotype things like Arya checking his PC, Kahlil browsing hobbyist media and maybe Guntr stargazing/ randomly doing training to his arm muscles XDD
2) is a very tough one! I can't wait to see the answers.
I wish you all the best too, thank you.
