Or then vice versa again: the Founders have been studying the Klingons, their supposed main adversary in Alpha, for several years without misleading preconceptions, relentlessly and meticulously finding out what really makes them tick, while Odo has just scowled at a couple of passing Klingons, dismissing them as Cardassians with funny foreheads.
Yet Odo is a policeman. He knows Martok is a crook, even though he can't quite put his finger on how and why. He pokes nevertheless, because that's what policemen do. And he finally provokes the reaction that he hoped for, even when he's hopelessly off base...
It's the "Armageddon Game" thing over again:
"I knew the recording about your death was a clumsy fake because you never drink coffee in the morning!"
"Uh, dear, I do. Pretty often in fact."
