who was that screaming?

When Julia fell into the swirly pool of time the other day. . i wondered who screamed for Grayson. .that surely didn't sound like the scream we usually .  .as if she's choking on a furball  . . .Nancy Barrett perhaps?  She was also working that day .. .

It didn't sound like Nancy Barrett to me - hers is a bit more high pitched and grittier than the Julia-stand-in scream.  Methinks it just might've been someone who worked on the show; maybe the girl who made the coffee for the morning doughnut table.
