How likely is it that the Tower captures Tuon to stop the Seachan and Matt leads the battle that topples the tower?  Big bombs dropping from the Rakens claws would be awesome.

Very unlikely given that the attack on the Tower is almost certainly underway, and Mat is almost certainly off to the Tower of Ghenjei.

And Mat's not to keen on the damane thing.  Remember Bode, his sister, is a sparker and training to be AS at the tower.

Obviously you don't have a sister.  I wouldn't mind seeing mine on the srong end of a leash.
