This is the chapter after ' The Tower Shakes ' so Egwene is fighting against the Seanchan raiders. Siuan, Gareth Bryne and their party get into Tar Valon and "rescue" Egwene and take her back to the Rebel camp.
I thought this was an anti-climactic way to write the end of the Seanchan raid. I would much have preferred it if after realizing what Egwene was doing the Tower Aes Sedai had sent a force of Sisters and their Warders up to the 22nd floor to help Egwene and rescue the Novices. Which is very likely what they would have done. Then Egwene would have been hailed and treated like the hero she was and been seen into bed along with the rest of the Novices who no doubt were as exhausted as Egwene was.
Then when the Tower Aes Sedai learned that Elaida had been taken by the Seanchan they would have decided to give it up and accept Egwene as the Amyrlin. Why not go for an immediate pay off ? Rather than delaying it with Egwene back in the Rebel camp contemplating overthrowing the Tower by force. A scenario that seemed rather far fetched considering what Egwene had just done in defending the Tower.
Siuan, Gareth and party could have been spotted early on by Tower guards and brought into the Aes Sedai centre of operations to explain themselves and then pitched in with the defense of the Tower. Everything else except them taking Egwene back to the Rebel camp could have happened as it did.
