Of course, being Dylan, he first registered a faint state of alarm with his ears going sideways and backwards at the same time. (Quite a feat for ears!!!)
Then when he realized there wasn't any danger, he, his ears (and his feet) relaxed.
I thought, though, that they still made an interesting foreground through which to peer at him.
That's when Dylan decided he wasn't so 'frond' of me anymore.
Oh well, you can't win 'em all!
