Whose mother is the fish?

Darl, in As I Lay Dying, seems to have a completely different sense of the world than most, if not all people. He is constantly questioning his own existence and the existence of others. Once his mother dies, he stops loving his mother because he thinks that she no longer exists, while at the same time he calls Jewel's mother a horse, and Varadaman's mother a fish, which doesn't make any sense at all seeing as they all have the same mother. Not only that, but hes got some sort of supernatural power, or at least that is what Faulkner makes it seem like. Darl seems to be able to accurately tell what exactly is happening in a totally different place. He watches his mother's death while he is away at town. The thing is, we don't actually know if these events are accurate. He could just be completely imagining these scenarios, but they are neither confirmed nor denied. The only part that we know to be true is that Addie dies while Darl is away. Darl is a very intriguing, but creepy character and I like him because of it.

Another interesting character is Vardaman. With memorable quotes like, "My mother is a fish." to give readers a sense of him, it seems as though Vardaman has absolutely no idea what is going on. He might vaguely recognize that his mother is dead, but she is most certainly not a fish. It also seems like he is at least somewhat able to understand Darl's mysticism. Or maybe he just goes along with whatever Darl says. It probably just comes with being very young and innocent to the world. I do have to wonder what was going on in his head when he decided that it would be a good idea to bore holes into his mother's coffin and face. Like, what? Maybe he thought she wasn't getting air. Hard to say.

Jewel is a bit of an ass.
