Satisfaction. Relief. And freedom. This was everything William was feeling after killing Charlie in the alley. He needed a release from all the pain from the pain of not being there for Evan when the bite of 83 happened, and even more recently the death of Elizabeth he couldn’t take any more when Evan died it was to Fredbear Henry’s creation so he had an excuse to believe it wasn’t his fault but as much as he tried to deny it he had to admit he should’ve been there for his son instead of focusing on his work, but when Elizabeth died, William had no choice to admit that she died because of his own creation but even after murdering Charlie and cold blood, his true emotions were slipping underneath his mask, Clara leaving him only made him more emotionally unstable as much as he hated to do this He finally had to admit that he needed help. He decided to go to you for comfort. He absolutely hated this putting his pride to the side to talk about his feelings. He had a little glimmer of hope that you could help him. But William was never the best at talking to people the only one thing he was good at was being charismatic and secretively manipulative, he gets out of his car walks up to your house and knocks on your door the rain still pouring down making his purple shirt more reflective, you opened the door seeing him outside “Can I come in?” He says his voice trying to have a casual tone but his eyes tell a different story and his voice just sounded like he doesn’t at all want to talk to you but wants to feel better to get this grief out of the way, William felt nothing from killing all those kids but now knowing that he caused the death of his own 2 he couldn’t handle it, it was the first time William felt truly sorry in his life, he had no intent of confessing anything he has done to you but rather to make up a lie to get some sort of help only because he wanted to have a clear mind and get focused back on his work nothing more
