[A bit mad? Well, perhaps, Radagast is very much on edge as he wrings his hands, distressed at Sams words.]

Do you mean he fell again? Oh Gandalf- [Then he paused, rooting around in his ear with one finger before looking back at Sam once more.] In the mine you say? I saw him just the other day- [A pause, did he see Gandalf? Ah yes, he remembered the white robes, he had thought it was Saruman at first, that had been distressing.] Ah yes, I've seen him, he gave me a bit of a scare but you know he's alive and well, don't you?
