Aerin's end?

[The Squatter of Amon Rûdh]

Certainly Asgon's words "Her heart was not faint, and patience will break at the last." imply some desperate act; but does he mean self-destruction or the firing of the hall? It's not unlikely that she killed herself, but the evidence is too scanty to prove the point for me.

Having said that, it isn't difficult to picture her waiting in the burning hall for the end in "patience and quiet". Suicide prior to this doesn't seem in character to me, and there's always a strong possibility that she was killed by Brodda's men.
