ISTM that she was set up several books ago to be the Federation's Romulan and then that didn't happen. That could be an editorial decision, I don't know. But you can't win everything.
I also agree with the new Praetor that Vulcan/Romulan unity is a pie in the sky dream.
The launch of Typhon I was also cool. That also seemed to be an editorial mandate. DRGIII mentioned he had two and I'll wager that was one of them.
