Welcome to Dubai. There are many nice hotels here. And within them, there are even nicer bathrooms...
Alone and in the center, the restroom attendant shakes, with his hands behind his head. On either side of him, both rows of toilets are occupied.
Androids use them. They're the Chessmen. Black uses one row of toilets; white uses the other. It's unclear as to what the hell Obadiah Stane was thinking, when he programmed a platoon of androids use a human restroom, before going to a volcano to launch an assault upon his old friend's son...
From the attendant's belt, a goblet hangs. It looks VERY much like the Holy Grail...
Simultaneously, the Chessmen flush. They turn, punch several buttons on their groins, and proceed out. The attendant shakes and shivers even more, as they march past him in dual files...
With a halberd, the Black Knight retrieves the goblet from the Arab's belt. He takes a moment to fill it at the sink. He throws a bag of gold into the attendant's money plate, and leaves...sipping the Grail, and "attaining eternal life," as he goes along...
If the Black Knight wasn't going off to a battle where he'd surely die, he'd get a chance to find out if the Holy Grail grants eternal life to ANDROIDS, as well as humans...
