The bridge led directly to a door Sam had never seen before: .

A bus that should have hit her swerved into a pie cart. A falling sign missed her by an inch but landed perfectly as a ramp. She tripped, fell through a manhole, and landed not in sewage, but on a plush red carpet leading to a door marked:

She dropped the penny.

The Grand Leprechaun, a tiny tyrant named Cillian, wanted the penny destroyed—along with Sam. But Bob had a theory. "Luck isn't a zero-sum game. It's a story. A tragedy with a happy ending is just a comedy with bad timing."

Inside was a penny. Not a lucky penny. The reverse: a penny from 1983, tarnished black, with a perfect drill hole through Lincoln's eye.

A falling anvil (Cillian's doing) aimed for her skull. Instead of dodging, she stuck out her hand. The anvil hit the penny, which flipped, spun, and ricocheted into a gear in the Probability Engine. The engine stuttered. The tsunami reversed. Every "bad" thing turned "good": coffee stains became winning lottery numbers, banana peels slid into perfect dance moves, and scaffolding reassembled into a golden bridge.
