Did do the search on Pam and came up empty.
Problem with IMDB is almost anyone (if you sign up) can post stuff to a resume, without having to back it up much.
No Pam Lawson character exists in my daily cast lists, which cover the whole show.
Also, none of those four airdates correspond to anyone named Pam:
# 6916...Airdate 12/10/92:
Bo, Carly, Carrie, Jack, Jennifer, Jo, John, Lawrence, Marcus, Marlena, Nicholas, Roman, Vivian, Shawn Douglas, Abigail, Brady, Guard (Don), Salem Inn Waiter, Worker, Man.
# 6925...Airdate: 12/23/92:
Abe, Austin, Billie, Bo, Carly, Carrie, Ivan, John, Lawrence, Marlena, Roman, Lisa, Detective, Charles, Bartender (Clint), Waitress (Linda), Ike, Man at Bar.
# 6941...Airdate: 1/15/93:
Bo, Carly, Jennifer, John, Julie, Lawrence, Marlena, Nicholas, Philip, Rebecca, Roman, Taylor, Dave, Lisa, Nora (Makeup Artist), Stage Manager, Josh, Man, Zeus (cat).
# 6942...Airdate: 1/18/93:
Alice, Billie, Bo, Carly, Jack, Jennifer, John, Julie, Lawrence, Marlena, Rebecca, Roman, Taylor, Tom, Victor, Abigail, Dave, Lisa, Tony Becker, Cop (Wilson).
Wonder why those fictitious airdates were added to Helena's resume??
