Also where ZSG is concerned, the actual impact on Bashir is fairly slight, dare I say incremental. I believe we discussed this recently in another thread and were more or less in agreement: Bashir has killed before in the line of duty, so we might say that Sarina goaded him into being somewhat more ruthless than he might otherwise have been, thereby setting the stage for further manipulation of Bashir in the future. Thus, the portion of ZSG that actually advances the DS9 storyline strikes me as fairly limited: Bashir has become vulnerable to future manipulation by Sarina, an agent of Section 31. That about sums it up.
Actually, I got the impression that the impact of ZSG on the continuity was rather greater. Didn't Bashir end up deciding to
leave DS9 with Sarina?
