That was sad, but I admit my first reaction was "better him than the Lying Cat". And if one of the grandparents had to kick the bucket, I suppose better it was kindly old grandpa rather than the nana who is more open to conflict. At least the latter keeps the plot going! Which is a rather inaccurate thing to say, now that I think about it - as if plots can only be kept going by negative interactions. In a universe like this one, though, that's probably more likely.
