I've read similar comments on this episode from time to time. It never really struck me that way, but I guess you do have to accept the bond between Kira and Ghemor for this story to work. It's always worked for me because I felt it was strong enough in Second Skin to be believable here as well, or for this to be believable as an extension of that. To me the issue in that scene is more Bashir's side of the dialogue, rather than Kira's. At least that's how it struck me in the past. There are lines where Bashir spells things out unnecessarily. But... not enough of a problem to really matter imo. Love the final scene on Bajor especially.
