Things he left open that I didn't like: --We don't see Leo reunite with the six after he flies off with Calypso --What happened to Apollo or the Spirit of Delphi --No epilogue about the seven after the war --No confirmation of Solangelo --Percy doesn't reunite with Grover or Sally PS-- Does anyone know at what moment Percy faced his fatal flaw? I can't remember or just didn't realize when it happened.
