This means many things 1. Sophitia would have stopped aging if she still survived, 2. Pyrrha will stop aging unless she gets killed, and 3. That means Patroklos is a malfested as well, since he is the youngest sibling. This could make a great twist in SCVI. This does imply that Sophitia might have killed herself or requested someone to kill her if she did not want to have the SE shard still in her body.
