In the episode "Broken Link," Odo needs to go to the Great Link to be cured. However, having been attacked by the joint Tal Shiar/Obsidian Order fleet, the Founders have relocated and don't want anyone from the Alpha Quadrant knowing where they live now. To that end, they have a Jem'Hadar pilot the Defiant with a device attached to the console that prevents the ship from recording its course.
After Odo's "trial," the crew seemingly beams back up to the Defiant and takes off with no further mention of a Jem'Hadar pilot or navigational jamming. So were they similarly escorted out of Dominion space?
