Disclaimer: I wish I was JKR and owned Harry Potter, but I'm not, so I don't.
Remember the pair of mirrors James and Sirius used to communicate with? This is a series of conversations they had through it. Give it a read! (And a review is another mirror to you; joining you in on the fun!)
Also, always, one or both of them is going to be in detention, and the one to start will always be James. Read on!
-Hey, tell me what's going on, Padfoot.
-I'm perfectly okay, thank you very much.
-Shut up and answer the question!
-Welllllllllllllllllllllllllllllllllllll... after you got Snape out, he bumped in Evans and told her everything. So now she knows all about Moony.
-So?
-So what?
-So what the hell is going on?
-She's talking to Remus.
-Can you listen in?
-No, and Merlin was an idiot. Of course I can listen in!
-Sorry, Sirius, I keep forgetting what a genius you are.
-Old Remus is telling her about the Shrieking Shack and the Whomping Willow...
-What's she saying?
-She looks worried.
-Not angry?
-Not angry at all. She likes Moony. Prefects, both.
-Don't remind me. What now?
-Evans just promised she wouldn't tell anyone.
-She did?
-Yeah. She's smiling and hugging him. Remus... wait a second, Moony's crying!
-What, Moony? You're kidding.
-Honest to god, I saw a tear there for a second!
-Dear Merlin, I'm in love with this woman.
-Don't I know it...
~Love, Bookie :)
