"I taught Harry how to conjure a Patronus, so I could still take credit for it," Remus
replied smugly.
"Oh yeah, and who taught you?" Sirius eyed him, feeling like he had won this
argument.
"I'll maintain that since I taught Harry, and Harry ultimately taught her, I still come
out on top here." Remus chuckled until Sirius punched him in the shoulder, knocking his
concentration so that he growled and lowered his wand.
"Get your wife and go home!" Sirius snapped.
"No! This is where we're supposed to be," Remus fought back. "I wasn't there when

"They're gone!" Hermione called back. "Sirius, the dementors are gone!"
"Good." Sirius glared at Remus and shifted into Padfoot.
Using the extra strength and speed afforded to him in his Animagus form, he
charged forward, letting the branches and bushes near the forest floor whip at his body as
he rushed into the shadows. Sniffing the air, he pulled out Harry's familiar scent and raced
