Years went by and Rachel could control her Archetype but her disappearance did not go unnoticed especially not with Michael searching for her the 3 years she was missing.
He searched night and day, the passing of their mother only made him intensify his search for his younger sister despite their parents believing she had passed on to the afterlife so they could begin healing and even hosted a funeral.
There was no clue however for him to work on, just random occurrences and he felt this was his sister communicating with him, her way of telling him that she is okay but this might all be in his head too and he was aware of this possibility.
Lucas' words replayed in the head of Michael and the more he thought about it, the more it made no sense. It was like Lucas was aware of what would happen and he also knew that his sister was special but there was no way to protect her.
