This is what happens when you listen to sad music while drawing. -.-
"Are you frightened, Twilight?"
"M-maybe a little... but I've got my book, and you'll stay with me, right?"
"I will, I promise. Until the very end..."
Of course, if you imagine Twi being literally stuck in a filling hourglass, things get a bit silly.
Or maybe nightmarish. Remember that scene from Aladdin? Brr~
