Julian Bashir: They broke seven of your transverse ribs and fractured your clavicle!
Elim Garak: Ah, but I got off several cutting remarks which no doubt did serious damage to their egos.
At the end of the episode, Odo has sent everyone affected by the telepathic matrix to a cargo bay. Sisko and O'Brien remove their com badges, throwing them aside before heading to the bay. After everyone is cured, Sisko straightens back up and, in the closeup, you can see that he has a badge on. In the next closeup, it's gone again.
In the scene where Kira and Dr. Bashir are talking, she points to her pregnant stomach and says "This is all your fault, you know" referencing that Bashir was the one who transplanted Keiko's baby into Kira. This is an inside joke, because in reality Alexander Siddig and Nana Visitor were an item, and Siddig was indeed the father of her baby.
