You Look Just Like Your Father [Sirius's POV]

Introductions

Padfoot shrank further into the bush as Harry passed him, not yet daring to be seen. He kept to the shadows as he trotted along in Harry's wake. Padfoot could tell that Harry was irate; his posture was stiff and his fists were clenched tightly around his trunk. 

They kept walking until they reached a street called Magnolia Crescent, where Harry sank to the kerb of the road, his anger having seemingly passed. He put his head between his hands, and that was when Padfoot decided to show himself. He made his way over to Harry cautiously, not wanting to startle the boy. But in his effort to remain silent, he stepped on an unseen twig. Harry's head snapped up and, upon seeing Padfoot, he jumped to his feet and stumbled backwards. His feet met his trunk and he fell unceremoniously onto the road, flinging his left arm out to break his fall. 

Padfoot knew now probably wasn't the best time to transform, what with Harry having just been startled half to death, but what choice did he have? If he didn't transform now, Harry would carry on walking, and he didn't have anywhere to go.

As Harry scrambled to his feet, Padfoot decided to just go for it. He smiled at Harry's look of bewilderment as he transformed back into a man. Where Padfoot had stood a few seconds ago, now stood Sirius. 

Sirius was aware that he must look a sight. His hair was elbow length and matted, his face gaunt and his cheeks hollow. Nevertheless, his haggard face split into a radiant smile as he gushed the words, "Hi, Harry."

Said boy just stood there, baffled, as Sirius searched his face for every detail, grinning like a fool as he did so. The resemblance to James was uncanny. Harry had the same hair, face shape, eyebrows and nose as James. Just like James, he was a handsome little thing. Just like James, his messy hair fell into his eyes, and a slight smattering of freckles dusted his cheeks and nose. Just like James, he wore thin, round glasses. The only things that weren't  just like James were his eyes. They were a striking emerald green colour. Lily's. Other than his eyes, he could have been James's twin.

"You look just like your father," said Sirius fondly. Harry just stared.

"Who are you?" He blurted.

"Oh, right, sorry. I... I'm Sirius Black," said Sirius, fearing Harry's reaction. "Don't be alarmed," he added, seeing the look of recognition that he had expected on Harry's face. "I come in peace," he chuckled, holding up his hands in mock surrender.
