“James! James?” But James no longer stood in front of her, not in human form anyway.
Instead of the handsome Head Boy, a rather large stag stood in front of her.
"What in blazes is going on?!" Lily hollered. "James, I want an explanation for this!"
With a small flash of light, the stag vanished and James was in its place.
"I've always wondered how I would explain this to you," James told her.
"Explain what, exactly?" she asked in forced calm.
"That Sirius, Peter, and I are Animagi," he answered.
"You three are Animagi?" Lily inquired quietly. "Why not Remus?"
"I'll get to that," James said. "Haven't you ever wondered why the three of us adopted our nicknames of Padfoot, Wormtail, and Prongs?"
"Yeah, I have" she conceeded. "But what's that got-"
"Sirius' a dog, Peter's a rat, and I am a stag," he interrupted. "We gave ourselves the nicknames based on what we can turn into."
"But, you said Remus wasn't an Animagus," Lily said slowly. "Why would he have the nickname Moony if he wasn't something like a wolf..."
Her voice trailed off, looking at James in amazement and astonishment.
"He's a werewolf, isn't he," she whispered in realization. "That's why he disappears for three days every month. How could I have missed that?"
"It took us until part way through our third year that we figured it out," James explained. "When we did, we found out that werewolves don't go after animals, so by our fifth year the three of us had become Animagi, and when we told Remus, we all got our nicknames: Moony, Wormtail, Padfoot, and Prongs."
"I...that's incredible," Lily said, gazing at James.
"Now, that I'm done talking, would you like to go for a ride around the grounds?" James asked.
"What?" she asked.
"Do you want to take a ride on my back around the grounds?" James repeated.
Lily thought for a second, and knew the only correct answer.
