Sea-Scientist!Snape
So much fun. I really loved the originality of this, the unusual location, the H/C, the great characters, and the leg-serpent is pure win! It was neat to read about the Neville's splinching, gruesomeness and all, 'cos I've always wondered exactly how that was supposed to work and canon doesn't have many clues.
Snape as a marine researcher is awesome! I love the legserpent's worried care for him - and how this time, Harry rescues him. So good, so very good! This is a wonderful storyverse and I'm going to happily imagine other adventures for them as Harry quits the Aurors, Severus recovers, the two of them get acquainted -- seasick Harry and all -- and they help the legserpent in her search for a mate! (And oooh - preg-serpent would be so much fun, too!)
