* This episode introduces the idea of blood testing to tell who is or isn't a Changeling. At one point Sisko points out that several people in a certain setting could be a Changeling, including himself. But Odo points to a bleeding wound on Sisko's hand. Humanoid blood, once it leaves the body, is dead tissue; "blood" leaving a Changeling's body would revert to shapeshifting jelly. This suggests a simple effective way to test a person suspected of being a Changeling. The idea is reminiscent of
John W. Campbell 's classic novella, "Who Goes There? ", made into two movie versions both called "The Thing ", in which scientists at an Antarctic weather base devise a similar test to detect who has or hasn't been infected by an alien virus that can perfectly mimic other life forms. Sisko's own father would point out a possible flaw in the test in the episode "Homefront".External links
