**Lily Evan's POV**

So Potter-the male one- does want Sophie back. I can tell. He hasn't even messed up his hair or asked me out since Sophia has been around. I just need to get them to talk to each other.

"Lily? Are you alright?" Sophia's voice snaps me out of my thoughts. "Marlene and Alice have gone to the dorm already. Are you okay?" she asks again.

"Hm? Yes, I'm fine. Is there anything that you and your brother used to do together that meant something to both of you?" I ask, purposely not using names. Sophia looks around before answering.

"Yes. We played guitar together. I still play. Why?" Sophia asks.

"I might have an idea on how to get your brother back," I reveal. Sophia grins.

"Really? What is it?" she asks.

"Not telling. Just give me a little time. I'll work on it," I promise before dashing up the stairs.

"Hey Rose! Was that Evans?" I hear Black ask.

"Lily-Flower?" Potter butts in using that horrid nickname.

"Ew. Do you really call her that? That might be why she won't go out with you," Sophia giggles.

"That's part of it!" I call down. Sophia and Black laugh and I can practically hear Potter's pout.

**Sophia Potter's POV**

"Is there something you wanted?" I ask Black. Black turns to me and grins.

"Me, you, Hogsmeade. What do you think?" Black asks. I raise an eyebrow and James gives him a death glare.

"I think you'll have to try a hell of a lot harder if you want to get a date out of me," I tell him before walking over to the Prewitts.

"Hullo boys," I smile as I sit on Fabion's chest due his laying down on the couch.

"Hey Sophie," Gideon smiles at me from the armchair.

"You're really light," Fabion tells me. "Like you weigh almost nothing."

"Thanks?" I reply, not really sure how to respond to that.

"Hey Sophia?" Remus asks. I turn to look at him.

"Yes? And just call me Sophie," I tell him. Looking up at him and his friends.

"Sure. And, uh, are you participating in open mike later?" he asks.

"Probably not," I say, shaking my head. I haven't sung since my fight with James.

"Oh come on, Sophie. I'm sure you're great," Marlene says. I guess her and the girls had wandered over.

"Yeah. You should do it Soph," Sirius says. I wince at the nickname. James used to call me that. It's probably my imagination but James seems to have winced as well.

"Please don't call me that," I say.

"I'll make you a deal. I'll stop calling you that if you sing with me," Sirius bargains. I sigh and nod.

**Marlene Mckinnon's POV**

"I get to pick the song!" I exclaim. Everyone shrugs and I go over to the song book and pick out the song "Lay All Your Love On Me" from Mamma Mia. I show Sophia and Sirius. Sophia lights up and I can tell that Sirius is trying to hide his excitement.

"I love this song!" Sophia grins. I smile back at her.

"I know it," Sirius says casually. James looks uncomfortable with the song choice. Good. Lily told me to make him uncomfortable. She also asked me if I had a guitar which was weird.

"Good," Lily says before climbing up onto the stage on the far left wall. She grabs the microphone. "Attention Gryffindors! Yes, hi. Sophia Rose and Sirius Black are gonna sing for us," Lily announces.

Sophia and Sirius get on the stage and grab two other microphones. Lily puts hers away and hops off the stage. The music starts up and there are some excited shrieks as the song is recognized.

Sirius starts:

I wasn't jealous before we met, Now every man I see is a potential threat

The two sing and I can tell that Sirius has fallen for Sophia in the short time that he's known her but Sophia seems oblivious. They finish the song and bow dramatically. Or, Sirius does and Sophia waves with a smile.

"Encour!" Alice shouts. Everyone picks up the chant and Sirius shakes his head while Sophia smiles wider. Sophia turns to look at her partner and he makes a go ahead gesture before getting off the stage.

"Hey guys! I'm obviously Sophia. Duh. I'll sing Dancing Queen if that's alright with you?" Sophia calls. Her words are met with shouts of approval. She smiles and waves her wand, turning the mike into one that you attach to your ear so that you can move more freely.

**Third POV**

Sophia starts to sing, and when she reaches the chorus, she grins and dashes out of the common room, everybody following her. The house dances through the corridors, Sophia's angelic voice projecting and bouncing off the walls. People of all houses join in the fun and sing along into the Great Hall. The professors look up to see what all the fuss is and their eyes widen comically. Except Dumbledore who just smiles in delight.

A seventh year Hufflepuff helps Sophia onto a table and she sings and dances to her heart's content. The song ends and cheers erupt, house rivalries temporarily forgotten as people laugh and hug one another. The teachers look on in awe. How had one girl so effortlessly united the houses. Mcgonagall's eyes find James Potter to see him gazing at his sister with sadness and pain and longing. Mcgonagall promises herself right then she will do anything to reunite the siblings.
