Talking of Sisko's behaviour, I just re-read Fearfull Symetry and The Soulkey, and both novels already start Sisko on his new path. He is appereantly given a vision by the Prophets of things to come, atleast that how it is comes across to me. And judging from what we know, it was probably a vision of the Trouble with the Ascendents.
[. . .]
So, if anyone wants to blame anyone for Sisko's path, please realize that it was all part of a bigger plan for the DS9 story arc already laid out, one that ultimatly never came to fruition.
I hadn't thought of tracing Sisko's behaviour back before RBOE, into the last books of the DS9 relaunch. This puts it into better perspective for me.
Agreed that the arc wasn't concluded in the context of the DS9 relaunch, but I wonder if it--or something like it--might be in the process of being completed in George's duology.
