I think Oeuf is one of those episodes that gets creepier the more you look back on it, not for the aesthetics, but how you see Will’s savior and God complex. When you have a better analytical understanding of how Will views his actions after the 3rd season, episodes like these make you see him very differently when you do a rewatch.
When you watch it the first time, you may see Will’s perspective on the Lost Boys as something of justified righteous anger. A man who is highly empathic towards boys who have lost everything and a sense of helplessness of what cannot be. This reflects Will’s fundamental strong belief that what has been broken cannot be repaired back to its original state. But those who have really come to know Will see something else in a rewatch.
Will is not only righteously furious of what has happened to the loss of innocence of the Lost Boys, but he is specifically angry that he cannot return what was lost. They have been tainted and sullied by violence and acts of evil and are therefore unsalvageable as a result. Hannibal even points this out to him that he shifted his focus to Abigail after his revelation of these facts. Abigail is still salvageable. She got touched by violence and evil and yet she came back from it. She can still be a normal girl with a normal life, because she is normal (or so he thinks). There’s something he can still do for her that he can’t do for the Lost Boys, because he saved her as a success. She’s the one good thing in his life and an investment.
But we saw how Will reacted when he realized Abigail wasn’t the normal girl he thought she was. She didn’t come back from the violence, she had walked alongside it and was still walking in it as she navigated the aftermath of her near death experience. So he had to destroy her and purge his mind of any thoughts of that kind of image of her. And when she was dying a second time, he let go of her bleeding neck when he realized she couldn’t be saved. And then he tried to convince himself that’s not how it happened.
Will loathes things that are unsalvageable or can’t be fixed by his own hands. And if you think about it through that particular lens and rewatch this episode, you see just how disturbing his mindset and justification of his actions is when it comes to how he views and handles the entire case.
