I completely get the fact that people would expect a Compulsion weave to dissipate before being delved. I get the reason why, but can you imagine wanting it to show up just enough to be detected, but never confirmed.

Consider this....you are investigating a murder. You find a fingerprint which you know belongs to a certain person. The way that it is placed leaves no doubt that they are the killer (just flow with the analogy). However after you have examined it, the finger print gets destroyed and well is just unrecognizable. You didn't make a copy of it or anything like that. Now all you have is your word that you know who the suspect is. You have no proof of that.

It is the ultimate distraction. If you're believed, good on you. If not, then it sews much discord into the entire situation. Its a fantastic play if Graendal even had a bit of knowledge that Rand was on the hairy edge of psychotic paranoia.

Do I think that Graendal is dead? Yes....with the end of the series seriously close, I think that there just isn't enough time. If this had gone down in book 5...no way. I'd not count her out....but since we're almost done with the series, I think that she's toast. To qualify this, if she does show up in the next book, I won't be suprised.

Oh, and incidently, we have seen on screen two weaves both being unraveled/picked apart. They were both gateways originally. Aviendha picked apart her gateway from the Tarasin Palace to the countryside on the way to the Kin's Farm. She did this successfully with no repercussions. The other gateway was from the Kin's farm to an empty field in Andor near one of Elayne's estates. Elayne is the one who picked that weave apart. It did't work out, and she ended up with a nuke weave which destroyed both sides of the gateway for a goodly distance.
