Absent any testimony to the contrary, my best guess is that her nude scene was done by a body double.
Here is the one “nude” image that is definitely she. An image super-brightened to an extreme demonstrates that her crotch has been digitally censored by a black rectangle.
The rear views could be anyone, and avoid any identification.
On the other hand, an actress named Catherine Toribio had a legitimate nude scene in that episode.
Is there a gif for this?
