. . . what Tuor was to Idril Celebrindal and Gondolin, except that Turin was
either flawed, cursed, or a mixture of both, and therefore did not form another
union of human and elf and brought destruction upon Nargothrond, instead of
trying to save it. The story of Turin is the story of many missed
opportunities, but certainly one of those missed opportunities was the love of
Finduilas. And Gwindor, like many other elves and humans Turin met, was
foresighted enough to warn Turin, but as usual to no avail.
I hope that helps. If you want something more specific a quotation would
help.

They seldom have to come back.'"
