Don stops at a diner to get some dinner. He's sweaty and not feeling well. As he steps up to greet the waitress he stumbles slightly, and the waitress says "geez mister, you have a bloody nose! Here let me get you a napkin." Don puts his hand to his nose and checks for blood. Just as he does he collapses. Several customers kneel down to check on him to see if he's ok. They roll him over on his back. "Mister, mister! Can you hear me?" Don's eyes are open and bloodshot, staring upward at the ceiling. He sees a fly buzzing along the tubing of fluorescent lamps. The noise in the diner grows faint, and you can just hear Don's slow, hollow breathing and the buzz of the fly. Don smiles and whispers "there you are..." The screen goes black. Don died of an undiagnosed STD. I don't know which one, whatever might cause a nosebleed.
