For those non-die hard fans of the original Beverly Hills 90210, we might have to explain just who  is.

She's the actress that portrayed Kelly's mother, Jackie Taylor. A bit of history on the character, who is reported to appear on at least one episode of 90210:

• She's a recovering cocaine addict;
• She married (and divorced) David's dad, Mel;
• Had a daughter, Erin, with Mel.
  

Hmmm, it's that last fact that has our interest piqued.

After all, the show's resident vixen (played by Jessica Stroup) is referred to by her last name, "Silver." Might her first name be Erin? Might she be Kelly and David's half-sister?

It certainly seems that way.
