Friends.
The most precious and valuable thing in all of existence.
That is why it hurts so much, when you lose a friend, especially a best friend.
Jacob is carrying Mordred, like Cain carried Abel.
He walks on the road that leads to the Lady of the Lake.
With each step Jacob takes, he feels like he is about to fall.
Mordred feels heavy in his arms but Jacob kept on walking, so that his friend may know peace.
Jacob arrived at the lake, where a boat was waiting for him.
Jacob placed Mordred on the boat.
He then watched, as the boat carried Mordred to Avalon.
All Jacob had left to say was;
" Goodbye, my best friend "
