Like His Sister (James x OC)

Full moon

Olivia's PoV

"Remus!" I call, "Hurry up, or we'll be late to dinner!"

"Coming!" He shouts back. He was better on the full moon days when I was close to him, supposedly because I had a similar, but sort-of opposite affliction to him. Similarly, on new moon nights, he was the only one who could calm me down. He came down the stairs and we started walking, together with Sirius and James, whereas Peter had gone ahead because he was hungrier, and Lily left with Marlene and Alice, my other dormmates.

"So, Liv, what happened on the first night back?" Sirius asked. My back stiffened. I felt a hand on my back, and turned to see James walking beside me.

"You don't have to tell us yet," he says reassuringly. My muscles relaxed. I smiled at him thankfully. Out of the corner of my eye I could see Remus death-staring James, specifically the hand still on my back.

"Remus, stop being an overprotective cinnamon roll!" I say. He frowns at me.

"Honey, I wasn't being an overprotective cinnamon roll!" He replies. I move closer to him, taking no notice of the odd looks I was getting from the rest of the group.

"Yeah you were, babe."

"No way, sweetheart," he sasses.

"Sugar, you were being waaaay overprotective and cinnamon roll-y."

"I was not, darling!"

"Cookie, you so were," I argue back.

"Nuh-uh, sweetie!"

"Ha! You already called me sweetheart, and sweetie is a shortened version of sweetheart!" I shout. Since we had arrived at the Great Hall, and most of Gryffindor heard us bickering, everyone looks at me.

"No! Since when!" Remus protests.

"Since you used it on me when we were fourteen!" I retort. Remus groans.

"Ahem," I say, holding my hand out expectantly. He sighs and gives me a Galleon. I grin happily and sit down.

"You started it and you finished it?! No fair!" Remus complains as he sits next to me.

"Hurry up and eat, you have to go soon," I point out. He finishes quickly and Sirius, James, Peter, Remmy and I all go towards the hospital wing.

"Madame Pomfrey?" I call.

"Coming dears," she trills. Remus sits on the bed.

"Alright, ready to go? I will be ready for when you arrive back," Madame Pomfrey says. We all troop out the doors. James slides the Invisibility Cloak onto himself, Sirius and Peter. I guessed they expected me to go up to my dorm. I had guessed correctly.

"Liv, go back to your dorm, we'll come get you when we're back," Sirius says, not unkindly, but looking expectantly at me.

"No, it's alright, I'll be sitting outside the Whomping Willow, so you can call me when you need me" I reply. They look shocked, but Remus nods.

"I'll definitely need her," he says, he turns to me, "you know the drill."

"Yup," I say.

"K," he says, then, giving me a hug, he murmurs, "Be safe, little one."

"You too, and I'm not that little," I grumble. Three weeks older than me and he thinks he's the King. Honestly! We walk down, all of us except Remmy under the Cloak. Peter transforms, hitting the tree's knothole. The other boys follow, going down the tunnel. I wait for a little bit. I hear Remus transform, and then some crashing and whining. He sounds hurt, and a little aggressive too. I don't bother changing into my Animagus form.

I slip down the tunnel, moving quickly through the Shrieking Shack to Remus' room. I push the door open and see a big black dog and Remus fighting each other. I look out the window. The moon is bigger tonight, which is worse for poor Remmy.

"Remus! Stop fighting!" I say sternly. He turns to me and I see that his eyes are still full of aggression. He swipes at my shoulder and his claws graze me. I frown, looking at him. I bonk him on the nose.

"Remus, that was very rude." I see a deer, a dog, and a rat all looking at me with disbelief. I see Remus cowering from me.

"Oh honey, come here," I say soothingly, sitting down. He curls up, putting his head on my lap and falling asleep almost instantly.

"He did say he'd need me," I say, turning to where the boys are, all of them having now transformed.
