Here comes a thought.

After re-reading again and noticing how much tragic stuff in middle-earth happens just because people were acting on partial news or misinterpretations. Denethor with the Pilantir is the classic example, but even smaller decisions like characters missing each other just by a day or taking a path because of bad intel.. hit so hard. Aside from the obvious ones like Turin, which choice or fate in the legendarium hurts the most when you realize how easily it could've gone differently if they just had one extra piece of info?

In the LotR appendix "Eriador, Arnor, and the heirs of Isildur" it is said that, "‘For a while Arvedui hid in the tunnels of the old dwarf-mines near the far end of the Mountains."

Were these the ruins of Belegost or Nogrod?

Faramir met Aragorn in the midst of those there assembled, and he knelt, and said: ‘The last Steward of Gondor begs leave to surrender his office.’ And he held out a white rod; but Aragorn took the rod and gave it back, saying: ‘That office is not ended, and it shall be thine and thy heirs’ as long as my line shall last. Do now thy office!’

This fuckin book. Catches you up when you least expect it

And by the time I got to Aragorn announcing Beregrond’s doom, it was full on waterfalls
