God, Casper is getting cuter each time I see him. I can't wait to see more progress on him. You're doing pretty well with the scripts too.
Here are my answers to the questions:
1. I didn't even think Arya would sleep at night but he would most likely stay up working on his laptop or something. Kahlil would maybe watch movies or eat some snacks? As for Guntur, I feel like he might just lay on the bed until he falls back asleep. (My first thought was him breaking into people's houses. Could also be a possibility.)
2.Guntur would probably eat something with a lot of protein like chicken or heartier meals. Arya might be more into things with caffeine or coffee flavored snacks? Like coffee cakes or something since I only remember seeing him with coffee in the demo, both during the introduction and that one scene where we gave him a can of coffee. (Or did he give it to us? I haven't gotten around to playing the demo again since I want to wait for the full release.) I can't imagine Kahlil picking anything other than sweets.
