William woke up early because he planned to look for his Master to seek his advice.
As an Alchemist, Albert was capable of creating Food Pills that allowed people to stave off hunger for three days at a time.
He was planning to get the pill recipe from the Full Kettle Alchemist and try to use it as an ingredient to strengthen the effects of his chocolate lollipop, which he would give to Chiffon.
Although the effects of his lollipop could last for three days when consumed, that only worked for normal people.
Chiffon was not part of that category, and William wanted to help her. The sight of her picking up trash to eat was something he couldn't erase from his mind.
Five minutes later, William barged inside his Fifth Master's residence and saw the renowned Alchemist snoring on his couch.
