He closes his notebook for the moment. "I have! On Earth I would've assumed a flower like this was radioactive, or a sign of a coming monster attack, but as far as I can tell there's absolutely nothing sinister going on here. It's nice."

At least he hopes it stays that way. He'll happily look at the pretty flowers for a while.
