Trials and Tribble-ations - S5-E6
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.
