Necklace question

May 2nd, 2005 — Wordman

The film Timerider featured a motorcyclist who accidentally goes back in time to the old west. Being hunky, he naturally beds a local babe and while basking in the afterglow, she asks him about his necklace, which is this misshappen hunk of metal. He informs her that his grandmother stole it from his grandfather and it was passed down to him. Later, in the dramatic finale, the motorcyclist is hanging from a helicopter, dangling a few feet from the babe. She reaches out and takes his necklace, just before the time portal closes and he is returned to his present. So, the big reveal is that the babe is the motorcyclist’s grandmother, implying that he is is own grandfather. Roll credits.

Since seeing this movie when I was 14 or so, my question has always been: who made the necklace?

Looks like I’ll miss my chance to ask those who might know how to resolve such a time paradox, as I’ll not be in Boston this Saturday. Thus, I’ll miss the time-traveller’s convention (of which, there need be only one). Perhaps I can travel back to it someday, necklace and all.
