Methuselah's Children
Sebastian is dead. Alexander stabbed him and fled into shadow. I, the player, know that Alex has made a horrible mistake. He has made Veronica (Carla's character) a bitter enemy. He has used he knife to draw Sebastian's Psyche into himself, which will probably have dire consequences. Worst of all for Alex, very few in the family will trust him now. They have no reason to fear him, but they will. At least one will hate him.

Corwin should have spoke to the family before releasing Sebastian. He could have tried to calm everyone down and convince them to give Sebastian a chance. Instead, he let Veronica convince him to release him from the sword. He was placed in the sword for his own protection, not ours. Corwin released him into a world of enemies and to completely doom him he took away his one defense. He let Alexander, who made it public knowledge he planned to kill Sebastian, spy on them with a pattern lens. When Sebastian was alone, Alexander struck. He didn't expect to be able to cross the shadows. He expected that Corwin or Bleys had a way to block the shadow from Alex's travel. Why else would they let him spy?
