Narrator's POV

Throughout the summer, Sirius and Remus instructed Harry on how to unlock his animagus.

First, he had to keep a mandrake leaf —that Neville happily supplied— for a whole month and he hand to chant "Amato Animo Animato Animagus" on a daily basis.

"It's a good thing you're doing this in the summer, puppy, because I remember the three of us swallowing our leaves whenever McGonagall entered the room." Sirius had joked

Then, once the month passed, they waited for a lighting storm to have Severus brew the potion (which the chewed mandrake leaf was a part of) and Harry drank it while reciting the chant.

And finally, Harry practiced his transformations for a month before finally unlocking it.

As soon as Harry transformed, Sirius said, "Even though you're a kitten, I am still going to call you 'puppy'."

"It make's sense that he's a black cat." Remus said, "Black cats are considered good luck here in England and also in Japan. But in the west, black cats have been looked upon as a symbol of evil omens like bad luck and death."

Tom didn't say anything about it, but he looked pleased.

Several days later, Sirius, Remus, Harry, and Tom went to the system of caves that the Greyback Pack of werewolves lived.

Remus himself was actually a member of the pack since he was bitten by Fenrir, but never actually lived with the pack.

The quartet was led to a waiting room by a Omega Werwolf —which is a low ranker— and waited for Fenrir.

After a few minutes, Fenrir Greyback entered the room.

Fenrir was a tall man with messy black hair, piercing blue eyes, a black beard, and wore a open black robe that revealed several scars on his muscular chest.

"Hello, my Lord, long time no see." Fenrir greeted Tom

"Hello, Fenrir, I assume you're well." Tom replied

Fenrir turned to Remus, "Long time since I've seen you too, Omega Remus."

Quickly changing his manner and greeting Fenrir, Remus said, "Greetings, Alpha. I haven't seen you since I was four."

"Anyways, to business." Tom said, "I believe our previous arrangement still stands, Fenrir?"

"It's does, my Lord." Fenrir replied

"Then our business is concluded." Tom relied, apparting away since he had much to prepare

Even though Tom left, Remus, Sirius, and Harry remained.

Remus started learning more about life in the pack, and the trio got to know Fenrir Greyback well.

The rumors about Fenrir that claimed he was a savage were quickly proved false as well as the rumor that he believed in werewolf superiority.

Remus learned that the reason Fenrir had bitten him, was because Remus' father, Lyall Lupin, made plans for werewolf hunts and forced Fenrir's hand.

Over the few days, Remus gained the respect of the other werewolves and gained the rank of 'Beta' instead of 'Omega'.

Fenrir had also grown quite fond of Harry or Lady Mercy and told the pack to treat said boy as his cub.

So Harry was 'cub' to both the Alpha and Beta (A/N: Remus and Fenrir shippers don't even think about it) of the Greyback Pack and therefore held power in the pack.

A few weeks later the trio returned to there home, and one night Fenrir —who was wearing a black shirt, jeans, and blue bandara— flooed into Grummuld Place saying, "Harry, I got two tickets to the Weird Sisters concert tonight, you want to come?"

"Yes." Harry replied, getting changed to a grey t-shirt and black shorts.

The duo flooed to where the concert was being held —the arena that the Qudditch World Cup took place— and took their seats.

The band started with their best hit: Do the Hippogriff.

Everyone was dancing to the beast and cheering.

The Weird Sisters then played, This is the Night.

About sixteen songs later, the band then moved on to the last song: Magic Works.

Since that song was a romance slow dance, Fenrir and Harry sat that out and prepared to leave before the mad rush of fans left.

Before they did leave though, Harry bought one of the Weird Sisters novelty shirts.

And they returned to Grummuld Place to drop Harry off.

"How was the concert, cub?" Remus asked

"It rocked!" Harry replied

"Good, but it's two am and you need to sleep, cub. Sirius is already asleep so be careful not to wake him." Remus said...
