Disclaimer I don't own Harry Potter.
Harry followed Snape outside of the shack, looking around and only seeing the boat that Vernon used to take them to the island "How did you get here?" Harry said looking up at Snape.
Snape pulls out his wand and a broomstick appeared out of thin air "I flew here Mr. Potter now get on." Snape said.
Harry looks up at Snape with worry and disbelief "But what if I fall." he said.
"I doubt that Mr. Potter if giving you have your father's skill on the broom, but if you are still worry then." Snape said as he casting as spell on Harry and broom "There Mr. Potter a simple sticky spell should put a end to you worry." Snape said in a cold tone as he helps Harry onto the broom.
"Can I hold on to you?" Harry said as Snape sets himself on the broom.
"If it will make things easy on you, then I will allow it." Snape said looking back at Harry "Now, if your ready. I am going to take us up now." Snape said.
"Okay but tell me when-" Harry was just about to said as Snape kicks himself off the ground, making Harry scream at first before calming down and starts laughing "This is amazing." Harry shouted smiling holding tightly on to Snape.
"Okay were going to faster now." Snape said as casts a spell on them and the broom.
"What did you do?" Harry said.
"A cloaking spell, were almost at London, and muggles are not allow to see us flying."
"Muggles?"
"Non-Magic people." Snape said as they were approaching London "Were going to be landing soon." Snape told Harry.
"Really? But this is so much fun." Harry said complaining "Do we have to."
"Yes I have a busy schedule Mr. Potter" Snape after they landed in a area with no people around and Snape cast a spell making the broomstick disappear. "Now, following me Mr. Potter" Snape said leading Harry down a street as they walked a few blocks and enter a small pub.
"Severus, good to see you again." the pub owner said.
"Can't right now Tom, helping Mr. Potter here with getting school supplies." Snape said causing the whole pub to go complete silence as everyone in the pub looked over staring at Harry Potter.
"Its Harry Potter." a man yells out as few men and women walk over to shake Harry's hands making him feel uncomfortable.
"Back off all of you, don't you people have more important things to do. Now away with all of you." Snape said coldly taking Harry's hand "Come along Mr. Potter.". Walking away form the crowd of people. While Snape was a little rude to the people back there Harry was thankful for his help with getting him away form them.
A pale young man with a purple turban cut them off as Snape was leading Harry to the back door. "P-P- Potter c-can't tell ha- happy I am to see you." the man said.
"Quirinus, doing well?" Snape said before looking back at Harry "Mr. Potter, this is Professor Quirinus Quirrell your defense against the dark arts teacher at Hogwarts." Snape said sounding a bit bitter about it.
"Hello." Harry said happy to met another professor and wanting to shakes his hand as Quirrell backs up a little, Snape eyed as scene unfolds.
"So-sorry no hurt f-fe-feeling Sev-Severus, I know you al-always wanted the job." Quirrell said.
"There always next year, now good day Quirrell" Snape said as leads Harry to the back door but not before looking back at Quirrell for a second as he leads Harry outside.
"Is Professor Quirrell always that nervous?" Harry said.
"No, Quirrell took a year off and hasn't been the same since." Snape said before taking out his wand and started tapping bricks.
"How did everyone back there know me?" Harry said.
"Answers later Mr. Potter" Snape said after tapping the bricks they started moving and opening up a archway "Welcome to Diagon Alley." Snape said.
