I felt so bad for abandoning all you faithful readers, I just had to pound this out and update tonight.

Disclaimer: I don't own Harry Potter, or really anything in this fanfic. Poor me.

Remus' POV

"Oi! Remus, get over here!"

Looking up from his old school Herbology book, Remus Lupin saw his best friend James' head in the fireplace.

"James? I thought you wouldn't be able to contact me, because of the Fidelius. What's going on," Remus asked, slightly confused.

"Just come, it's important. We need you, now." Remus frowned. James sounded worried, something he hadn't been in years, not since Sirius had run away from home back in 4th year.

"I'd be over in 5, but I need somebody to take me there."

"I'm coming."

Remus stepped back and watched as his old roommate and metaphorical brother spun into the fireplace. Dusting himself off, James turned to Remus and offered his arm with a grim smile.

The first thing Remus saw on the other side was the carpet. He'd tripped out of the fireplace and face planted. James helped him up and led him to the living room, where Remus collapsed on a couch before seeing the person opposite him.

"Wormtail! What are you doing here?" He hadn't seen Peter in years, and he looked terrible.

"That's actually why you're here, Remus," said James, coming up behind him.

"What do you mean… Oh," realized Remus. They were going to make him secret keeper instead of Pete. But why? He voiced his thoughts and Lily replied,

"Peter thinks he can't be trusted, that he'll betray us somehow." At this, Remus glanced at Peter suspiciously.

"What's up, Wormtail? Why are you doing this?"

And Peter began to tell them the story.

It had all started when James and Lily began dating. They'd spent more time together and with Sirius and Remus, causing Peter to feel left out and lonely. One day, a student Death Eater had confronted him, and to make a long story short, Peter showed James, Lily and Remus his left forearm. On it, like a dark spot on his soul, lay the Dark Mark.

"This is why I asked you to change Keepers," Peter muttered.

Remus was in shock. Sweet, naive Peter Pettigrew, a Death Eater? What must have driven him to that point?

"Alright everyone, let's start the process now," James added, his voice shaky.

Remus snapped out of his thoughts and joined the others in a circle in the middle of the room. James began the incantation and joined Remus' and Peter's right hands together. Peter said his part, and then it was Remus' turn.

"I, Remus John Lupin, do solemnly swear…" As he recited the oath, Remus flashed back to his Hogwarts years, and the Marauders' Map… 'I solemnly swear I am up to no good… Messrs. Moony, Wormtail, Padfoot and Prongs do proudly present the Marauders Map…'

"Remus? You in there?" Lily's soft voice brought him out of his reverie.

He looked up to find that everyone was staring at him expectantly, waiting for him to say the last part of the oath. Then he realized, he didn't know the address of their new home, or even the town. He reminded ten of this and waited patiently as they filled him in.

"Godric's Hollow? Really? Don't you think it's a bit obvious, and that this is the first place he'll look?" Remus wondered if the Dark Lord had realized that the Potters were under the Fidelius Charm, then remembered that with Wormtail as a Death Eater, the Dark Lord would probably know already. Then he had an idea.

"Pete? What if you were used as a sort of spy? On Voldemort?"

Peter had obviously not been expecting this, and gave a little jump at the sound of his name. Lily and James had also not thought of this, but it was clear they thought it was a good idea from their expressions, Lily hopeful, and James jealous he hadn't thought of it first.

"You mean… I could be useful? To the Order and Dumbledore? And you guys?" Peter stammered. For the first time since receiving the Mark, he felt hope.

See? I said they'd be getting longer.
