Naomi does notice the odd creature's movements as does Eve. Neither of them have any idea if the other familiar does have a lead, but it wasn't like they knew where to start either. So, the doctor lets her familiar slither to the ground and follow the other to the pile it seems headed towards. Any potential lead was a good lead.

And with that done, Naomi turns back to Allura. "I can do that..."

Though, now she wonders if she'd see Allura as a projection anyway as it would be her spirit.
