Yes, Yes, the twins.  The beautiful luscious twins, together until the end.  They were best friends to Stephanie Kaye and were together until the end.  Erica thought that she got mono from some creep from St. Mary's school at the dance, but didn't.  Heather thought that she had it too, because she kissed the exact same guy!!!!  Well they didn't have mono and made up at the end of the episode.  Erica had sex with some guy and got pregnant...much to the dismay of Heather she had an abortion.  Heather tried to steal Wheels right out from under L.D. when she was in the hospital.  Heather made out with Wheels at a party but then Wheels dumped her sorry ass.  It was pretty funny.  Heather helped direct Lucy's movie and the twins liked to get drunk...well that's about it for the twins.
