Val and Rhonda - I was so happy when I found out that they got married.  Earl says in Tremors 2: Aftershooks the Val married a good woman, now he didn't say that he married Rhonda, but it's probably safe to say that they did tie the knot.  Especially when they ended the first movie with them kissing.  It wasn't love at first site though because Rhonda didn't fit any of Val's standards, but being stuck with each other in the desolate town of Perfection for awhile they seemed to grow closer.

Earl and Kate - Now Kate didn't appear until Tremors 2: Aftershooks, but I thought that I should include Earl and his lady in this too.  Kate was Miss October '74 and Earl kept a picture of her to remind him not to chase the things he'll never get, but can you believe that he would meet up with her in Mexico some 21 years later!?  Plus they both thought when you spend a couple of days almost getting killed, you start thinking you should date more.

Burt and Heather - This gun crazed couple seemed to be a very umm.. happy couple in Tremors, but we found out in Tremors 2: Aftershooks, after the break up of the Soviet Union and the none threat of global war, Burt and Heather soon separated.  Heather went to her sister's leaving Burt in the basement of the house (Yes, they did fix that big hole in the wall from the Graboid).
