OK. Another bit of weirdness that came to me in a dream; fortunately, it was just before I woke up and I managed to get the gist of it down before it evaporated altogether.
A fairly common fictional theme, particularly in televised fiction, is that of two people in some sort of relationship having a fight and one of them leaving - to go to work or whatever - and suddenly dying. Surviving one then has guilt about the last words between them being unpleasant.
The idea was to correct this situation using time travel. This does not require the ability to actually prevent the death or change the past in any other material way - merely to correct the bit about the last words being harsh ones, thus removing some of the guilt and presumably helping the survivor.
