The next two hours slipped away quickly. First, the student met again with , who, once she was done explaining what they were going to do this year, started her lesson, on the environment.
Bill didn't really care about this, and was getting a little bored during the hour. After this morning, he was careful not to sit in the back of the class again. Léa had come to sit beside him. He didn't mind her presence. On the contrary, he prefered that she was here.
Then, it was the music class. In the classroom, there were some instruments, that didn't seemed to be used very often, since most of them were covered in dust. Students weren't sitting in front of tables this time, but in circles. They had to use a solid support to write. The teacher asked every student if he knew how to play any instrument. Most of the class didn't play any instrument. Some of them knew how to play the flute, the trumpet, some others the drums. There were some pianist too. Dipper probably played the biggest instrument in the room: the sousaphone. As for Mabel, she claimed knowing how to play the piano, even though Bill knew well she was just making music with randoms sounds from a synthesizer. Léa was among the non-musician group.
When it was his turn to answer, the young man, after hesitating for a second, answered he knew how to play the piano.
After that, the teacher asked some supplies for her class. The list was shorter than the others though, since the they were mainly going to sing. How was singing out loud in front of the others classmate useful at all? Bill asked himself. He didn't find the answer.
Nothing interesting happened from that, until the bell, rang, for the last time today.
Every student rushed outside, as if they had been kept in prison for years. Bill waited for the mass to be gone before leaving the room. In the hall, Léa was waiting for him. She followed him, without saying a single word, until they reached the School's entrance. She then headed to a bus, turned to Bill, and said:

- S-...See you tomorrow?

- ...y-yeah, sure. Bye...Léa.

She smiled again, before getting in her bus. Once the vehicle was gone, Bill looked around to see if John had arrived. He was not here yet, but he didn't wait for too long. John came by few minutes later.
Although relieved to be out of this "prison", he stayed quiet towards John, simply walking to his side. So it was his "guardian" who started the conversation:

- So. What about your day?

- My d-..? Ah!..Long. By the way, there's some stuff you need to sign.

- We'll take care of this at home. What happened to your face ?

- Ah, er...Tough luck.

The talk stopped there, with John letting out a sigh, and Bill simply quietly walking.
Before getting in the house, John stopped, sighed once more and stared at Bill :

- Look, Harley thought it would be a good idea to find you a…"companion", so you can learn responsibilities.

- What do you mean…?

- You'll see.

Bill pushed the entrance door, put down his backpack, took out his shoes. He headed to the living room. He saw Harley sitting on the couch. She looked at him, smiling weakly:

- Yvan-, she started before getting cut.

- Bill.

- Ehm, yeah. I was saying, you should go to your room.

Bill slightly opened the door to his bedroom. At first, he didn't saw any changes, closing the door behind him. He leaned on the bed and stretched out.
Something suddenly jumped on him, startling him. He jumped back up.
What just jumped on him was a little creature mostly white. He held it in his arms. It was a cat. It was a male with a pure colored fur, with light gray stripes all over his body. It almost seemed like he had greyish "gloves" on his paws. His nose and his pads were black. His tail had different shades of grey, darker at the top. He had beautiful green eyes, that were somehow reminding wild grass.
Bill stared at the animal, stunned. Then he finally understood.
"So you're the one John was talking about." He said, as he put the feline on his knees. The cat meowed as he rubbed against him. "A creature using his appearance, his sweet side to seduce humans, so they will fulfill his every needs? Here's a creature I appreciate". Bill grinned. He stood up to get back to the living room. The cat, like if it was a reflex, jumped on Bill, and rested on his shoulder. At first surprised by the sudden move of the feline, the young man quickly grinned again.
In the living room, Bill looked at Harley and John.

- So, what do you think of your new companion? Harley asked, giving him a patient smile.

- He's nice. I like him.

- And what are you gonna call him? said John.

- Hmm…...

Bill stared for a few instants the animal.

- Tac.

- Tac? That's….Original.

Later, while they were having dinner, Harley fully explained to him how to take care of his cat, but mostly, that it was HIS role to take care of him. It wasn't something that bothered him. After all, deep down, he and Tac were the same.
