So, I was thinking the other day, was it ever explained how the General Martok changeling cheated the blood test in The Way Of The Warrior? I've watched that episode a few times and can remember no explanation for it in the two parter nor in any episode after it. Having changelings find out how to cheat the test might've been interesting, but it seems like TWOTW writers tried to ignore this inconsistency by never addressing it, that way they could have their twist later in the story even though it doesn't make sense.
