Anyone can be a changeling now?!?! Worf and Garak go on a field trip to discover Doctor Bashir was replaced with a changeling a month ago while he was off at a Space Doctors Conference with Space Pharma Girls. While Bashir was away his changeling participated in all sorts of evil doings... using the last roll of toilet paper without replacing it, draining all of the smoke detector batteries, using the free sandwich punch card at Quarks. Truly vile things. While at a Jem'Hadar internment camp, Worf joins a fight club and Garak deals with his daddy issues.
