Plus one. Jily is pregnant...at hogwarts.

Shock.

"I'm Pregnant."
"James?...James?" Lily continued. James stared at her, frozen in shock. "James, please say something." She said.
He stepped back to lean against the wall and rubbed his chin. "I just, uh. I-I don't understand, uh...how this happened. You're taking the potion." He finished.
"I know... I think it happened early Janurary, about a month ago, after the party."
They were both silent for a second. Lily, on the one hand, was desperately scared that James would leave her and never speak to her again. James, however began to speak, proving her wrong.
"Well, ok then."
Lily spoke with the most shock in her voice he had ever heard.
" You're ok with this?" She asked.
"Well, it was a bit of a shock, at first, but I think we'll be fine."
"I will?"
"We will." James said. "So, you're about a month along then. You probably won't start showing until...April, so that's manageable. You'll just not have the fire whiskey at Sirius' post game parties, which shouldn't be a problem since you never have it anyway...and we won't even have to tell anyone, because by that time, school will be over in a matter of weeks..., given that, the baby will probably come around early September, or late august." He said.
Before he could begin rambling on, Lily began to kiss him ferociously. She flung his arms around his neck, and their kiss lasted for several minutes. "James Potter, I love you."
"I love you, too." He said. And they took off into the great hall.

"Are we going to tell them?" Lily asked.
"Sure. Why not?...are you okay with that?" He asked. Lily nodded and they continued on, hand in hand. They approached the rest of the marauders and James pulled them aside by hand. "What's going on, prongs?" Sirius asked.
Lily, still clutching her stomach, looked around and made sure no one was near the corner where they were all now crowded. "We're going to have a baby."
Upon hearing the news, Peter fainted, Remus cupped his mouth with his hands and Sirius began to ramble.
"Ok, glad you have realized that you're made for each other and everything, but seeing as how that's not going to happen any time soon, can I please get back to my waffles?" Sirius asked.
"Actually," began James, as he helped Peter up. "It's going to happen in about 8 months, They all looked at Sirius waiting for the meaning of James' sentence to dawnupon him.
"Oh my god." Sirius said, as he blanched.
"Relax, Padfoot, it's not happening to you." Said James.
James and Lily both looked at each other and began to kiss. Their kiss deepened as Sirius spoke, "Oi! No more of that, we don't need twins, do we?"
And at that moment as their laughter subsided, Lily realized that she wasn't in this alone at all. The man she loved, and their three best friends would never let that happen.
