Here's a plot!
Spider dies on the Sea Dragon and wakes up in a world where Mr. and Mrs. Sully love him and adopted him when he was just a baby. In this alternate reality, many things are the same, except for this one change. Confused and wary, Spider can’t understand why they’re being so kind to him and assumes the worst. Haunted by the harsh truth of the life he remembers, he recoils from the love he’s offered, convinced it’s a lie or some cruel joke from the Great Mother. As he keeps his guard up, the Sullys are upset and confused, wondering why their son seems so afraid to open up to them.
