Taking leave of a brother permanently is a profound and emotional moment that involves understanding and acceptance. It’s about recognizing the bond you share and respecting each other's feelings and circumstances, even when parting ways. Wishing him well reflects genuine care, and acknowledging his understanding, pity, and fellowship shows a deep appreciation for the connection that endures beyond physical proximity.

In the context of the quote, Lymond emphasizes that parting is not just about saying goodbye but about appreciating the emotional support and shared experiences that define brotherhood. Acceptance of each other's journeys, driven by circumstances beyond control, is essential in maintaining the bond and respecting the nature of their relationship.
