Sure enough it was Harry's third full moon and Sirius said it was his last one here.
"If you guys say he's been in a bad mood the week it's a full moon send me a letter and I'll come help you OK?"
They nodded. "We'll be fine. You need to help Remus. Your school days are done which means it's our turn to help him." Hermione said.
He knew she was right but was still worried about his pup.
Harry was having a little trouble getting his eyes to stay green today. Luckily it was Friday which means no school tomorrow. Snape had handed Harry some wolfsbane earlier that afternoon.
After lunch they had transfiguration and were learning how to be an animagus. They had told her that they were one already but listened like they didn't know yet. They could tell that Harry wished he was an animagus and not a werewolf.
"Can anyone tell me how they find out what their form is?" McGonagall asked.
Harry raised his hand. "Potter?"
"If you already have a patronus that's what you're animagus will be. If not when you take the potion you'll lose sight for three minutes and feel it, hear it's sound, find out how big it will be when you feel it's strength and get a picture of it after. And then your patronus will become that when they learn how to make one. Like you Professor, your animagus is a cat which means it's a cat."
Everyone looked at him in surprise.
"Very good Potter, ten points to Gryffindor."
Even she was a little surprised at how he knew that.
'Did he look at his friends and help them when they did that?' she wondered.
After transfiguration they were done for the day. Harry was tired so he went to take a nap.
A few hours later they were in the Shack.
"Alright pup, this is the last one I'll be here unless you have a bad week and get aggravated OK?"
He nodded. A few minutes later it happened. Sirius could see he was doing good. Fighting himself and trying to get control.
'Come on Harry, you can do it.'
A few minutes later he saw him scratching himself hard.
As usual he was exhausted after he was done. This time Ron came to check on him.
"I'm OK, let's just go to the hospital wing."
They nodded and headed to Madam Pumfry.
