I love what Gordon wrote in his will.
"I'd just like to take this opportunity to say that, in my own way, I love you all, even those I don't particularly like. That's you, Beryl." [The exact quote, as found on page 22.]
I also thought it was funny when Stephanie went to go change into her new outfit, and when she came back, Skulduggery was all like, "Surprise! It's the clothes! :D"
