The smirk on Sirius’ face when Remus saw him coming towards where he and Peter stood outside the great hall was the first sign that he was up to something. This being confirmed as he strode up to them waving a small vile in the air.
“Moony! Wormtail! I have the best thing ever right here” he grinned wildly as he shoved it in their faces. Remus raised an eyebrow at him, a look of amusement on his face at his friends antics. As if sensing their confusion Sirius began to explain,
“ok so you know how James keeps ditching us to hang out with his mysterious girlfriend? who we all know is just Evans but whatever, I think it’s time we prank him.”
At this Remus and Peter perked up, the former reaching out to take the potion into his hands.
“So what’s this then? You gonna change his hair colour or something?” Remus asked as he inspected the bottle. Sirius just grinned again, reaching out for the vile.
“Better”
Genuinely intrigued now at what Sirius could have gotten his hands on Remus looked around to see if James was anywhere near by, meeting Peter’s similar gaze of curiosity.
“Come on Pads, just tell us what it is” Sirius’ grin somehow widened at Peter’s wining tone and seemed to decide to show mercy. He hid the vile in the pocket of his leather jacket and slung his arms (the best he could) around Remus and Peter. Remus listened as he explained that the potion would cause James to break into song and serenade whoever he fancied.
“Oh that’s perfect Pads! It’ll be bloody hilarious and since he’s our friend we wouldn’t want him to genuinely get upset and since literally everyone knows it’s Lily he’s into he’ll only be embarrassed at his shit singing abilities” Sirius nodded at this,
“I know, I’m a bloody genius”
They separated and made their way over to the Gryffindor table, sitting in their respective seats, Peter leaving room on his left for James who would be slightly late due to quidditch practice. Peter handed over James’ cup and Remus looked around for Lily whilst Sirius poured the potion in with James’ regular drink. Spotting her near the end of the table, closer to the entrance than the boys were he waved slightly, smiling as she waved back.
“Alright, everything’s ready, plan it cool boys” Sirius said, schooling his face into its normal resting dramatic-bitch face and hiding the empty potion bottle.
Remus heard James before he saw him and nudged Sirius and Peter with his feet under the table. Perfectly casual, Remus smiled at James and waved him over, the man smiling back and running a hand through his messy flying hair.
“Hey Prongs, how was practice?” Sirius asked as he sat down, Remus catching the little smirk that Peter was hiding behind his own glass. Before James answered though he took a large gulp of the water in his glass, probably thirsty after practice- oh how perfect this is going already. Remus thought, amused. They all tried to stifle their laughter as James sat up straight, blinking a few times before raising his wand with a beaming, love stuck smile. Eyes wide he watched as James casted a spell to project his voice across the entire hall.
“THIS ONES FOR U BABE” his voice sounded around, the tables becoming a mixture of hushed, excited and humorous voices. With another flick of his wand music began to play from seemingly no where.
Did I mention that I'm in love with you?
And did I mention there's nothing I can do
And did I happen to say?
I dream of you everyday
But let me shout it out loud, if that's okay ay ay
Remus laughed as James stood proudly on his chair, singing loudly and completely ignoring the Professors who were telling him to get down. He had a surprisingly good voice which kinda ruined half of the plan but still he was looking in Lily’s direction as he continued.
If that's okay (Hey!)
James fucking beamed as he jumped down from the chair and started making his way over to where Lily was, clicking his fingers to the beat like the showman he is.
I met this person that rocked my world like it's never been rocked
And now I'm living just for them and I won't never stop
I never thought that it could happen to a guy like me
Remus’ eyes widened almost comedically when at the last second he realised that James body wasn’t turned towards the pretty redhead but to the dark haired boy opposite her at the Slytherin table.
But now look at what you've done, you got me down on my knees
James dramatically dropped to his knees in front of a alarmed looking Regulus and clutched theatrically at his shirt over where his heart would be. The music almost drowned out by the gasps of shock and amusement from the spectators
Because my love for you is ridiculous
I never knew
(Who knew?)
That it could be like this
My love for you is ridiculous
My love is R-I-D-I-C-U-L-O-U-S!
Ignoring James’ serenade for a moment Remus snapped back into action, jumping up just in time to hold Sirius back from possibly punching or hexing James. Despite a pissed off and in protective-brother-mode Sirius in his arms, Remus actually thought the whole thing was bloody hilarious even if their prank went a bit off road.
(R-I-D-I-C-U-L-O-U-S!)
It's (Ridiculous!)
Just (Ridiculous!)
Regulus mirrored his brothers pissed off look, scowling at the singer in front of him with his arms crossed but it was easy to see the cracks in his mask; the light blush that flushed along his cheeks and the flustered yet fond gaze he had whilst James attempted to twirl him around.
And I would give my kingdom for just one kiss
With an exaggerated wink James finished off the song before he was pulled in by the tie by a determined Regulus who kissed him. In front of everyone. Remus wolf whistled, happy for his two friends and the rest of the crowd joined in. It was cute until he felt a strong tug and Sirius ripped away from where Remus had been holding him.
“Pads-“ Sirius for once in his life didn’t even look back at Remus’ weak attempts to stop him as he marched over to where James and Regulus stood, barely a foot apart.
“JAMES FLEAMONT POTTER YOU HAVE A LOT OF EXPLAINING TO DO”
James just blinked a few times, seemingly coming out of a daze before realisation dawned on his face, quickly followed by horror, embarrassment and then anger.
“ME!?” He turned and stalked towards Sirius, pointing his finger at him. “YOU SPIKED MY DRINK DIDNT YOU!?”
Sirius spluttered at that before yelling back “YOU KISSED MY BABY BROTHER!”
Regulus cleared his throat, glaring at Sirius from behind James.
“Oh har har Sirius, I kissed my bloody boyfriend get over it he’s a free man.” Shocked silence followed as everyone, including James, realised what he had just said.
“BOYFRIEND!?” Sirius somehow yelled louder, “ARE YOU DEFILING MY INNOCENT LITTLE TINY BABY BROTHER JAMES!?” James simply raised an eye brow at his best friends antics and Remus had never been more proud of him. Before he could answer though Regulus slid up next to James, putting his hand around the other boys waist. He looked Sirius dead in the eyes and went,
“Yes he has.” With a bit of a smirk that greatly resembled the one Sirius had adorned earlier. Remus winced at the scream that Sirius let out before he slapped his hands over his ears, shut his eyes and began loudly muttering under his breath about not wanting to know his brothers love life. Sighing his signature exasperated sigh Remus climbed over the table (like Sirius had done) and made his way over to the three boys.
“Well you asked” Regulus’ eyes shone with triumphant and Remus snorted as he carefully curled his hand around Sirius’ wrist. Turning to James and Regulus he found himself smirking too.
“Just make sure you’re using protection Reggie” he winked at his friend, ignoring James’ quickly spreading blush before pulling a malfunctioning Sirius black away from the crowd.
