Dark Lord Severus (слэш)

Prompt 2025-167
Sexy American vs Sexy Brit (like Selleck vs Rickman in Quigley Down Under) MACUSA Auror/Unspeakable Assassin vs British Dark Lord.
When Lily and James Potter fled to America to hide from Voldemort, pretending to be Muggles, Jimmy and Lizzie Crawford, they thought that would be the end of their Dark Lord problems. Unfortunately, nearly 20 years later, their son, Jerry Crawford, is summoned in his capacity as an Auror to help deal with the British Dark Lord problem. The twist: the current Dark Lord isn't Voldemort.
