London, 1979. It was just another simple spying mission, so James didn't expect anything to happen. As it escalated he just should have left and returned into safety, when he saw the little brother of his best friend lying in his own blood, facing a certain death. Death Eater or not, he couldn't leave him there, could he? But inviting the enemy into your home in the middle of a war couldn't possibly be a good idea.

Golden boy, Lion boy; Tell me what it's like to conquer. Fearless child, Broken boy; Tell me what it's like to burn. (...) In which a very nosy James Potter notices that every weekend, when everyone falls asleep, Regulus Black sneaks into an abandoned fifth-floor classroom, and he can't help but try to find out what the little Black is up to.

The Marauders are starting their fifth year at Hogwarts; Remus is starting with a massive scar across his face - a byproduct of the increasing severity of his furry little problem, which is a definite cause for concern despite his insistence that it it's fine. Sirius is starting with the memories of a certain morning at 12 Grimmauld Place in August: memories that he might not ever forget, yet is desperate to cloak underneath the facade that every is fine at home and that he and his parents just sometimes encounter minor disagreements. James is starting his fifth year, yes, but more importantly, he is starting phase five of his plan to woo Lily Evans: somehow his friends seem doubtful that he might succeed, but James, being James, is in no lack of confidence. And Peter, well, Peter is starting to wonder just why he puts up with these people, and if he should really be feeling sorry for Lily Evans, and maybe if he should have asked to have been sorted into Hufflepuff.
