Severus, Half-Blood Prince of Denmark III: Four Funerals and a Wedding

At last, the long-delayed third installment of the Daftest Crossover Ever. Parts One and Two are here. Basically, what you need to know is that a young Severus Snape has drunk a Plothole-Plugging Potion, landed in the sixteenth century, and is now happily wandering around Europe saving characters in various Shakespeare plays from themselves. In the last installment, he met Helena, a young French witch who is now definitely NOT in love with Bertram, and Diana, a Florentine who invited him along to Verona for her cousin Juliet's wedding.

Summary: Snape meets Romeo and Juliet. (Almost) everybody lives.
