HP: Unexpected Storms

He remembered his name: Salazar Slytherin.

Salazar Slytherin found he couldn't speak, unless Parseltongue counted as human speech.

He stubbornly believed something was missing, and not just his memories.

Those memories seemed unrelated, locked away in some corner of his mind, waiting for him to awaken them.

Until he met a boy with pale blond hair.

He didn't know who he had once been. He was Draco Malfoy.

Draco Malfoy was a genius, so much of one that he was rebellious by nature.

He thought he could lock away his true self and avoid a lot of trouble that way.

Until he met the green-eyed savior.

The comedy version (spoilers):

Green-Eyed Savior: "Are you insane? You're hurting yourself and everyone else! Fine, you messed with the two of us, but you also screwed over the original Draco and Harry!"

Genius Malfoy: "That really was an accident. You know what they say: Fate is like a wild horse that's broken free, never to return."

Green-Eyed Savior: "Don't change the subject. The way you act makes me wonder if a dog ate your brains."

Genius Malfoy waves a huge black dog around, telling it to spit his brains back out.

Green-Eyed Savior: "You're hopeless. Don't tell anyone you know me."

Couple: GGXSS (pseudo Draco/Harry); secondary couple: GGAD, no fixed pairing

Follows the original canon, including elements from the films

Theme: Changing fate doesn't mean controlling it
