Talk:Too Many Pinkie Pies/@comment-99.13.33.41-20121118221248/@comment-99.13.33.41-20121119011249

They knew only the names of three of them, one of them being Pinkie Pie. That's the only thing they knew.

All of the other Pinkies acted exactly the same, so it seems obvious the only one with actual will was Pinkie Pie.
