Why is Paul finally able to remember the whole truth about what happened to his eyes? *

On Friday, December 1st, Paul heard Erik use the name Castor. Erik was angry, and in a rage, but the name Castor stuck with Paul and the memory returned. Paul remembered the spray paint from when he was four. He remembered that Erik and Vincent Castor had sprayed something on a wall, and he remembered Erik accusing him of snitching of Castor. Then Paul remembered the assualt and the truth, as well as his mother's intervention.... and some story about an eclipse.
