Feeling like a dunce, but I immediately forgot Kuzya's phone number before thinking to call it. I hadn't gotten in the habit of jotting things down yet.
Also- any tips on making the potion? (can it even be made?) I picked up the items, scanned them, and am at a loss for what else I should be doing. Finished the game with the items in my bag and it doesn't seem like I got any special dialog..
