And for Egwene to then use it in kind to expose Sheriam before the Hall....brilliant.

It was very interesting to see Egwene's first reaction...which did not appear to include the possibility of Vering being Black. Her first thought was "you haven't held the Oath Rod", her 2nd thought was "then you've had the Oaths removed", and it wasn't until after Verin confirmed she was BA that Egwene entertains that thought.

But most interesting for me was not the revelation of Verin being Black, not the revelation of the list she compiled, but rather, the fact that she doesn't believe that Rand, nor anybody else for that matter, truly understands how the DO works and how his battle will be fought. There's loads of insight in those comments, but pulling out details will be very difficult.
