Her model was unique, but she didn't have a "face" back then. When Monty decided to unmask her literally 1 episode later, given it was thrown in at the last minute (and to likely hammer in her connection to Yang), Monty used pretty much a Palette Swap of Yang.

But, as noted by Chish some time ago, her head, mask aside, before and after showing her face, are different. Particularly the hair style.
