Joseph Sisko claims that a changeling could take a person's blood and hold it inside themselves, dispensing a few drops to fool a blood test. Without a constant oxygen supply, wouldn't the blood congeal or something? Or could the changeling mimic a working system of lungs and internal organs to keep it supplied with oxygen? And if Joseph is right, why does Starfleet keep using blood tests right through the rest of the series as a way to find Founders?
Great Moment :
Armed Starfleet officers beaming down to the streets. Ooooo... scary...
When the wormhole starts opening and closing for no apparent reason, Sisko fears a Dominion invasion of cloaked warships. Soon after, Earth starts suffering from sabotage attacks and evidence is uncovered that the Founders have infiltrated the planet. Sisko and Admiral Leyton convince the President to institute a state of emergency, and armed Starfleet officers are on the streets within hours.
