In the Pale Moonlight - S6-E19

In the Pale Moonlight - S6-E19
Visible crew/equipment: After Jadzia plays devil's advocate with Sisko, he tells her she would've made a decent Romulan. Then, when Sisko passes the camera as he walks around his desk, the blue T-mark is visible on the floor behind Jadzia. (00:06:10)
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.
