"It is rare for Jaeger pilots to survive the death of the other - rare out of the Drift and even rarer when one pilot dies in-Drift. In a moment of violent death, during a battle, it would take a strong and determined will not to psychologically reach for the person they feel closest to, whom they know best, who is theirs beyond all shadow of a doubt."
