Woolsey: Have you detected any physical anomalies that might be related to his visions?
(Carter looks at him questioningly.)
Woolsey: Sorry. Force of habit.
This line is most likely just Woolsey (Robert Picardo) apologizing for reneging on his promise to Carter that "I have no intention of getting involved in the day-to-day operations of the base" and acknowledging that he can, as he admitted earlier, "on occasion, be a bit of a busybody." However, the mention of a "force of habit" is possibly a reference to Picardo's previous role as the Doctor on Star Trek Voyager.
