It is possible. Still, I think it is liklier it is either Hana or Sophia here, since I see the beginning of a mini skirt at the pics edge. Alternatively it could be some noise in the pic.It's hard to be certain, but I think you can just make out the strap and buckle for the garters on those background legs, just like the ones Andrea is wearing. I'd say that's another house girl, she's just a little taller (by height or by camera angle) than her companions.
