The Zetas are running scared because the gravity wave spells curtains for them as well as the Earth. Hell, their planet is practically falling apart, shedding dust all over the place.

The moment that gravity wave hits, Planet X is toast.

This probably explains why Nancy is making so many mistakes recently, and excusing it by saying her own state of mind and preconceptions are influencing the Zetan message. She never mentioned that before... it's only become an issue since the Gravity Tsunami was incoming!!!!

The Zetan panic is affecting her connection. Soon they won't be able to communicate at all. After all those years with talking aliens in her head, Nancy must be feeling pretty lonely already.

At least the death of Planet X means any Earthly survivors won't have to deal with any pole-shift!
