No, it was Sirius himself who just had to stand out. With his jeans and leather jacket, he essentially looked like a biker - the matching tattoos on his arms were thankfully hidden by his jacket. Remus knew his friend had adopted that outfit to further distance himself from pure-blood society and especially his family of fanatics. After all, whenever Sirius got the chance to do something that could potentially annoy the Black clan - meaning his mother Walburga nowadays - he did it without any hesitation.
Having all apparated back into the park in Little Whinging, they were now walking down Magnolia Crescent to their destination, Sirius clearly enjoying the looks of disapproval he got from its inhabitants thanks to his outfit.
"Somewhat boring here. All the houses look alike," Sirius then commented. "Exactly the kind of neighborhood my mother would hate."
"Your mother hates everyone and everything, Padfoot," Remus reminded his friend.
"Yes, but it being a Muggle neighborhood would enrage her especially," Sirius replied, speculation that she probably would suffer a stroke if being forced to visit this place.
Walking up to the front door of Number 12, they rung the doorbell and then waited.
The door was moments later opened by Veronica Evans. She gave them a neutral look, though Sirius attire clearly sparked her disapproval. She also gave Dumbledore's long beard a curious look. "Yes, how can I help you?"
"Veronica Evans? We need to speak with your husband, Thomas Evans. It concerns his cousin, Lily Potter nee Evans," Dumbledore told the woman, having taken off his bowler hat.
Only now did Veronica connect the dots. The somber mood of these people, their dark clothes and the way the old man was acting... She quickly told them to come in. Inside it was quite obvious they were still moving it, but they did manage to find a somewhat comfortable seating arrangement.
"May I introduce ourselves. I'm Albus Dumbledore, Headmaster of the boarding school Mrs. Potter attended. This is my Deputy, Minerva McGonagall. These two gentlemen are Sirius Black and Remus Lupin, good friends of the Potter family," Dumbledore introduced their group.
"You... have news of my cousin Lily? It's been years since I've last seen her," Thomas asked as soon as he could without appearing rude, already fearing the worst.
"Sadly, it now is too late," Remus told him, taking no effort to hide his own grief.
"Great Lord..." Thomas needed a moment to accept the news that his cousin Lily was dead. "What... what happened?"
"On Halloween eve, Lily Potter and her husband James were murdered by a terrorist who was attempting to kill the entire family. Only their toddler son Harry survived," McGonagall told them somberly. "They got betrayed by someone they thought was their friend."
Both Evans were silent for some moments, trying to process these horrible news. Even though Thomas hadn't seen Lily in years and Veronica had never met any of them at all, this senseless murder hurt them deep inside.
"This...comes all of a sudden." Thomas clearly was trying to find words.
"We all needed time to understand that they are truly gone," Sirius said, speaking from experience.
They then gave the couple some time to process the news they had been given and answered a few inconsequential questions. Clearly, the unexpected bad news was taking a toll on them. It was only after a while that they approached the question both of them were wondering.
"What happens now to their son?" Veronica asked.
"I fear this is a very complicated matter. There are many things the late Lily Potter did not tell her extended family," Dumbledore tried to explain.
"It think it's better to just show them." Sirius then ignored calls from the others to wait and transformed into his animagus form.
Almost half an hour later, things were finally cleared up.
First both Evans had to be revived after fainting from seeing a man turn into a dog, and then they needed some time to calm down and accept that they had not turned insane. It took several further demonstrations of simple magic like levitating objects and and applying and reversing Transfiguration on simple items, for the couple to start and actually believe in magic. Everyone was patient with them, knowing how difficult it had to be to see something that went against all they knew.
Of course, first Sirius got seriously lectured by McGonagall on how foolish and dangerous it had been to do this, as there could have been better ways to show them. She also made him apologize for scaring the couple like that, forcing him to promise he would learn to be more tactful.
Thomas tried to get things into order in his mind. "So, you say that Lily went to a magic school, and that's why she was away for so much of the year?" Seeing confirmation, he sighed. "Is that why Petunia started to resent her?"
"It is connected," Dumbledore said. "I did not reveal this to anyone, but she actually at first was fascinated by magic and wanted to join the school as well, but when I had to explain to her that it was an inherited trait that she can't learn, it turned into resentment."
"You mean she cut her sister out of her life out of simple jealously?" Veronica asked, feeling this to be quite petty.
"Only partially," Remus tried to explain it properly. "Lily told me that Petunia probably would have come to accept this and just move on, if not for their parents fanning the flames. The way they always awed and praised Lily's magical abilities while dismissing anything Petunia accomplished as inconsequential, turned it into the hatred Petunia feels nowadays."
"Lily did try to reconnect to her, but that failed spectaculary, also due to James being too ignorant of non-magical things. The last time they saw each other was Petunia's wedding, and that relegated them just as background guests as a social obligation and little more.," Sirius explained, having heard the last bit from James.
