Don't mind Harry, he's a goob. I had fun writing, so I hope you have fun reading.
DISCLAIMED!
"SIRIUS!" Harry cried as Sirius dissolved into nothing after Bellatrix killed him. "NOOOOO!" Bellatrix cackled evilly like the witch she is and ran off. Time seemed to slow down for both Harry and Remus.
Harry's only thought was to run after Bellatrix, but when he went to chase her, he felt something hindering him. He looked down and saw arms wrapped around him, holding him back. Harry struggled against Lupin, and finally managed to break free. He took off after the crazy witch.
Lupin watched as Harry ran off, undoubtedly to get Bellatrix. His heart was breaking at the thought of what had just become of Sirius Black. Unable to even stomach being in the same room at what had happened-almost happened, Remus firmly reminded himself-he apparated himself back to Grimmauld Place; the designated meeting spot.
"Good god, if they don't take this well, I might as well say goodbye to you right now, Sirius. You're so dead, Padfoot." Twin arms snaked around Lupin's waist, squeezing tightly.
"I know that. That was scary, Remus. Scariest prank I've ever pulled.. I don't want to do that ever again." Sirius nuzzled his face into Remus' back, his hold tightening even further. Remus sighed, his face softening in sympathy. He turned himself around so he could look down at the smaller man instead of just his arms.
"You said you wanted to do that. You knew I didn't approve. What would have happened if you hadn't apparated out in time? Or if Bellatrix hadn't also agreed to your strange idea?" He pressed his nose into Sirius's hair, wrapping his arms around his very much alive Sirius Black.
"I could've died, I know. Just kiss me, idiot." Sirius tilted his face upwards smirking up at Remus who gave a kindly smile in return.
"Always." Their lips met in a soft kiss, Sirius making a happy sound in the back of his throat. He brought his arms up to loop around Remus's neck, but a loud cough interrupted them. They both separated and turned around to see Bellatrix just stepping out of the fireplace.
"Where's my promised galleons?" Sirius laughed and stepped forward to place said money into his evil cousin's hands.
The end.
This was just something that popped up when I was re-watching Harry Potter. I like Sirius, you know?
And yeah, Bellatrix doesn't act like that. Go with it.
