Danny: (After seeing death memorials of his family and friends that reads, "Gone But Not Forgotten") Mom? Dad? (Sees Mr. Lancer's memorial that reads, "Gone") Where's the Nasty Burger?
Dark Danny: (To young Danny; near the Nasty Burger) Strange how one massive fireball of highly combustible condiments can ruin your whole future.
Danny: The medallion?
