י לֵב--יוֹדֵעַ, מָרַּת נַפְשׁוֹ; וּבְשִׂמְחָתוֹ, לֹא-יִתְעָרַב זָר. 10 The heart knoweth its own bitterness; and with its joy no stranger can intermeddle.
Or as Stargirl put it:
"I'm disappearing, Leo. Like Dootsie's trick, except this is real. Who are you if you lose your favorite person? Can you lose your favorite person without losing yourself? I reach for Stargirl and she's gone. I'm not me anymore."
