Deliberate mistake: The dying Vantika hides his consciousness away in a portion of Dr. Bashir's mind. At one point, "Bashir" (heavily cloaked in clothing and shadows) comes up behind Quark and makes sure his demands are clear. At this point, it should still be unclear just how Vantika is still "alive", and whose body he is using. However, when he shoves Quark away, for a fraction of a second, Bashir's face can be seen under his hood. They were true to plot in using the right actor (though he shouldn't have been seen), it is possible some might have spied the secret earlier than the show meant to reveal it.

Question: Wouldn't Sisko have created a paradox by identifying himself by his real name to James T. Kirk before returning to the future?
Answer: No more so than Sisko posing for a photo in the 21st century while pretending to be Gabriel Bell.
Answer: His last name is something Kirk will forget, since he was on temporary assignment and essentially passing through.
Chosen answer: No. He's given his name, that's all. Nothing there that might lead to a paradox. If he's gone into detail about his time travelling, that might cause an issue or two, but simply stating his name does nothing.
