The 2 main problems with the Graendel dunnit theory was why she was in Caemlyn and why she wasn't disguised. I could never think of a reason that would be in-character for her, so I never accepted the theory until it was confirmed. Also means that some of my assumptions about her / the situation are wrong.

Why was Graendal in Caemlyn?

To murder Asmodean?

Lets get the obvious out of the way. Graendal may have a motive to kill him to try to stop Rand's attacks on the Forsaken, but she has a better motive to keep him alive. She would want to know how much Rand knows, is he Lews Therin, does he know where she is, etc. And she could also take him to Shayal Ghul for a higher position among the Forsaken. There's still no motive here.

To place spies?

She would have been spying on Rhavin. Obviously. They would have been among the servants who stayed in the palace when Rand took over.

Looking for Rhavin's *angreal?

She has no reason to believe that Rhavin has *angreal, where he might keep them, or how he was protecting them. Unlike Sammael who kept them in his rooms and showed them off.

Looking for Rand's *angreal?

They are in Cairhien.

Meeting with Rhavin?

Ok, so maybe she didn't know that Rand attacked that morning. That would make her spy network less efficient than we expected, but it's not out of the question. She could have stayed for recon when she found Rhavin dead and Rand in charge.

Why wasn't she disguised?
