He says goodbye to his Mother, Stepfather, Chiron and all the friends he still has at camp half blood and leaves for camp Jupiter. he rejoins the Legion, where he slowly begins to dig his way out of his grief. Frank and hazel help him through it, but the one that really pulls him out, is the one person he least expected to.
