He met with Sirius where they agreed they would: the bench where he scared him as a dog two years ago.
"Ready?"
"Just get me out of here." Harry said, and Sirius apparated them both to Grimmauld Place, but twelve wasn't there.
"Where-" Harry was about to ask, when Sirius pulled out a piece of paper with the secret written on it with a neat cursive handwriting.
Out of nowhere, 12 Grimmauld Place appeared. "Fidelius Charm," Sirius explained.
When they entered, he was greeted by a tight hug from Hermione who ran towards him, followed by Remus.
"Harry!" Hermione embraced him, and he embraced her back.
He walked up to his room to put his stuff, Remus helped him with it.
"You lost weight," Remus noted, "have you been eating?"
"My appetite hasn't been-"
"You should eat." Remus said firmly. "Mrs. Weasley made a delicious stew."
Sirius has offered his home to serve as the headquarters of the Order of the Phoenix- a group of wizards and witches who fight Voldemort and his followers. During the First Wizarding War, Harry's parents were part of the Order as well.
This meant there were always people in 12 Grimmauld Place: The Weasleys, all of them except for Percy, who sided with the ministry, the real Mad-Eye Moody and a young witch named Tonks. Snape would occasionally be around too to Sirius's dismay.
Harry, Hermione, and the Weasley kids were kept out of the meetings, but George and Fred found a way to circumvent that minor inconvenience.
"Extendable Ears!" They announced, as they held up one of their extendable ears.
And so, they all would eavesdrop on the Order's meetings.
"…Malfoy is the Dark Lord's main man in the ministry, they're planning on infiltrating most departments, but he seems to be particularly interested in the Department of Mysteries because of the…" Snape was sharing the intel he gathered, when Mrs. Weasley found the ears and pulled them down towards her.
"What's in the Department of Mysteries?" Hermione wondered, and so did the Weasley kids, but Harry was already deep in thought about something else.
Malfoy… Snape was obviously talking about Lucius, but Harry was thinking of Draco. This is it.
After the meeting, the kids were all called down to dinner, but Harry slipped away. Snape never stayed for dinner, so Harry knew he'd need to act fast.
"Professor," Harry stopped Snape, as he was getting ready to open the door.
"What do you want, Potter?"
"How is Draco?"
Snape looked at him, raising an eyebrow. "He's fine."
"Do you think you could give this to him?" Harry passed him a folded letter.
"I can't do-" Snape started saying, but Harry interrupted him.
"Please!" He hates that he's begging Snape, but this seems to be the only way of communicating with Draco.
Snape says nothing for a moment before sighing and begrudgingly taking the note from Harry.
"Did you sign this with your name?" He asked.
"No," Harry answered, "but he would know it's from me."
"Would the Dark Lord know?"
"No."
"I better not regret this."
