Sirius and Auralia meet alone; enough said.
"I knew you where the leopard before!" he said proudly, "none of the others believed me...! and when i caught the scent of the trail; you, i began to follow" Sirius was speaking loudly because he was so excited to be right but she put a hand to her lips to motion him to be silent. She took his hand and pulled him through the trees to where it lay. He stopped, realising why she had told him to shut up and but he also lost for words because the astounding animal was breathtaking.

 "What? that stupid git" Sirius said joking "He's just trying to get into your pants and don't say i didn't warn you!"

 "Well. He shall be dissapointed..." Auralia said firmly, "Because i'm not planning on wearing any pants to the ball."

“It is all for the greater good.”
