Aggie was slotted for life as a Keeper, a woman who put herself between her charges and danger. A genuine crisis of conscience kicks in on her second assignment and ends with her charge in hiding and Aggie in cold sleep for a while.
Ikvaro was Aggie's instructor on the moon base and his heart broke when she disappeared and was reported dead. Informed that she was alive and needed his help, he resigns his commission as instructor and heads out to the stars to find his woman now that duty no longer stands between them.
She thaws, he looks into her eyes and she is no longer alone in there. She has gone from Keeper to Avatar and there is no protocol for this manoeuvre.
