*grins* Honestly, I didn't even think of the "no one lives completely happily ever after" bit until you just pointed it out. The last line was pretty much pure "@#*% you, Marvel!" ("...and in my story, Steve and Jan and the Vision don't die, take that!").

In the original story, Little Kay is trying to make pieces of ice spell the word "Eternity," and when Gerda comes in and hugs him, the ice pieces dance for joy and then land back on the ground and, by pure happy accident, have formed the right word. It seemed like a much more Tony kind of thing to do to actually solve the puzzle, so I gave him a technically insolvable math problem that he could finish with a trick.
