'But the Entwives gave their minds to the lesser trees, and to the meads in the sunshine beyond the feet of the forests; and they saw the sloe in the thicket, and the wild apple and the cherry blossoming in spring, and the green herbs in the waterlands in the summer, and the seeding grasses in the autumn fields…So the Entwives made gardens to live in…We crossed over Anduin and came to their land; but we found a desert: it was all burned and uprooted, for was had passed over it. But the Entwives were not there. Long we called, and long we searched; and we asked all folk that we met which way the Entwives had gone. Some said they had never seen them, and some said that they had seen them walking away west, and some said east and others south. But nowhere that we went could we find them.' - Treebeard, The Two Towers.
"But what about these Tree-men, these giants, as you might call them? They do say that one bigger than a tree was seen up away beyond the North Moors not long back…But this one was as big as an elm tree, and walking - walking seven yards to a stride, if it was an inch."
"Then I bet it wasn’t an inch. What he saw was an elm tree, as like as not.”
"But this one was walking, I tell you; and there ain’t no elm tree on the North Moors.”
-The Shadow of the Past, The Fellowship of the Ring.
It’s a tiny moment in the series, and probably just inconsequential conversation, but I’ve always held onto some naïve hope that what Hal saw was an Entwife in the north of the Shire, and that there is still a chance that the Ents and Entwives may meet again in Middle-earth after the shadow of Sauron passes.
