To put it mildly Val Lehman and Elspeth Ballantyne hated each other. Val has made no secret of this.
According to rumours Val was getting a concession because she lived so many miles away from where they filmed PCBH. Not just Val, but anybody that lived 20 miles (example) away from the studio received this travelling expense.
Anyway, after a few years Val moved closer to the studio and omitted to tell the studio that she had moved (thus she should not have been receiving the pay out)
Elspeth found out and as Val said she 'Couldn't tell the producers quick enough' This led to a running fued between the two.
I read all this on a website years ago, but damned if I can find it now. It's only recently that Val & Elspeth will even appear at conventions together. Val despises her.
thanks for filling us in, I'd just read that they didn't get along so well. Gotta say, you'd have never had guessed there was that much hostility though from watching the show.
