The sudden touch to his back makes him start, but then he holds himself still again, trying, like Crichton, to take the world one thing at a time.

It's been a long few months, and Arthur has completely forgotten about the flower stuff that was happening last time he set foot in this world. So it's with absolute confusion that he says: "I'm... what?"

His voice rasps, but doesn't catch, so getting those petals out does seem at least to have helped. For now.
