After watching the red- head go further into the house, William debated on following him. However, the other's words struck him in a way that they never had before. He remained where he was, thinking of the other and what it meant for the words that came out. He quickly regained his own composure when the redhead came back, fully intent on leaving.
"Sutcliffe, it wouldn't be wise for you to go through with doing whatever it is you plan on doing." He said, knowing the use of the other's last name upset him, but couldn't do anything about it.
Grell stopped and looked over to the other, shaking his head. "Just stop it. Stop telling me what I should or shouldn't be doing." He replied, doing his best to keep his thoughts in line. He didn't want his true thoughts and feelings to surface, being he knew it'd be worthless. Instead, he glared at the other male. "My importance to you only matters when it comes to work, and nothing more." He said, picking up his death scythe. "If I am to die, so be it. At least, then I won't have to deal with this turmoil in my heart." He said, then left, slamming the door behind himself.
William watched the other leave the house then thought to himself. He thought the other had known how much he did mean, yet William had always been unable to say. He sighed, thinking back on the other's words, waiting. When he eventually felt the something wasn't right, he got up and left the house, creating a portal and stepping through.
Afterwards, he had his own scythe and trekked through the small forested area, heading to where he knew the Phantomhive household was located. He didn't know what to expect, but, he did find himself beginning to feel worried, though he thought of it as concern. He knew he should have stopped the other from his recklessness, but he didn't. Yes, he knew that Grell was one of the strongest reapers they had, but he also knew that the redhead wasn't performing at his peak either. Others were going to be a lot stronger while the other was quite weak.
William slowly followed along the path, stopping when he had noticed a few drops of crimson on said path. He sighed, hoping it wasn't what he thought it was as he moved once more, following the path once more, looking up when he had heard the sounds of a fight in the distance. He began to move quicker to where the sounds were present. He stopped when he arrived at the residence and jumped on top of it, watching the two fight. He first watched the redhead, familiar with the other's tactics. He seemed to have the upper hand, though; William remained to help in case the tables were turned.
He then shifted his attention to the demon butler that Grell was against and shook his head slightly, knowing that the other could change things at any point. However, he was surprised when the other didn't just yet, though William knew better than to think he wouldn't try something.
He shifted his attention to the redhead once more and decided to keep his gaze upon the redhead, watching the way he used his scythe, but especially the grin that the other was wearing. Even though he wouldn't admit it, it did alarm him somewhat. After awhile, he watched as Grell lost his footing and shook his head before attacking again, but what made William inwardly gasp was the fact that one minute Grell was up and fighting, the next, he was on the ground unconscious.
William thrust out his scythe when he saw Sebastian try to take advantage of the situation and came over. "Not today." He said then picked up the redhead and left before any more damage could be done.
