I think we all forget how funny Elfhelm is (among his many other excellent traits).
A tall figure loomed up and stumbled over [Merry], cursing the tree-roots. He recognized the voice of Elfhelm the Marshal.
'I am not a tree-root, Sir,' he said, 'nor a bag, but a bruised hobbit. The least you can do in amends is to tell me what is afoot.'
‘Anything that can keep so in this devil's mirk,' answered Elfhelm. 'But my lord sends word that we must set ourselves in readiness: orders may come for a sudden move.'... 'So much I have heard but no more. And now I must busy myself with my lord's commands. Pack yourself up, Master Bag!' He vanished into the shadows.
I fully believe that Elfhelm and Merry were fast friends for the rest of their lives — Elfhelm being grateful to Merry for the service he gave to Éowyn and Merry being grateful to Elfhelm for allowing him to ride with his éored — and for all that time, Merry was always and exclusively called ‘Master Bag.’
