Severus Snape finds himself alive when he shouldn't be, and much to his dismay back inside his teenage self. No idea how he had managed the impossible feat he is determined to turn the tide of war before Voldemort ever has the chance to try and target Lily. What he does not expect is that Remus Lupin is in the same boat as him [rated m for strong language, mentions of child abuse]

Kreacher disobeys Regulus' command to go home. Regulus survives the cave. Kreacher knows that Regulus is in danger and only knows one blood traitor that might give him the chance at surviving. Can Sirius forgive his brother? Can Regulus find a way to destroy the locket and give himself redemption? (warning for talk of past child abuse, strong language)
