Alberi suddenly grew his interest in Potions after the attack. Potions could help a lot, if not in the battle itself, but after it - healing, torturing, killing, finding information. And the boy was sure to learn anything he could that would be useful. During the attack he felt useless... And he didn't like that feeling. He didn't want to do nothing. He had no idea how to act and that might have been against him - this time he had luck but the next time he might not be that lucky. So he agreed with himself that he should be prepared. Rather safe than sorry, as he often said.
He entered the room just before the professor decided to start the lesson. Nowadays he wasn't his usual on time self. He was definitely distracted much more than usual and was always in his head, which was pretty much the same like before but not because he wished to be away from people. Making his way quickly to a free seat, he listened to what the professor told them to do. Girding potion... Well, that's something he definitely needed a lot...
Not wasting time, he immediately began to make the potion. Alberi was careful to put the correct ingredients, in the correct order. He might as well need it in the future and is was good to know what to do. Step by step he brewed the potion, sure to remember it afterwards. He watched it turned into different colours, to its final green one. This was probably one of the most colourful potions, honestly. As soon as he finished it, he left it aside and began to memorise the instructions.
