Good questions - anyone want to take a stab?
I do think Illya has an internal compass - my hubby does, which makes me crazy. I don't, which annoys him - a perfect match.
I'm especially interested if anyone can come up with an answer to the carving question... was it that processed it compacted it and made it become so much heavier? Or was someone asleep at the wheel?
What say you, my cousins?
