There's a reason for the abject terror in Iggy's eyes: Look at the look on Heathcliff's face, then look at where Iggy Nutmeg's comb-hand is.

Happy 400th post, Heathcliff.

Edit: Either what I thought was happening is happening, or Heathcliff's body is twisted at impossible angles, which makes Mrs. Nutmeg's comment even creepier, considering the huge, dead cat on their laps.
