I don't know. You say there can be only one, but the experiment that created you could have been used on another person in secret. It's a possibility, even if it's not very likely.
[Cough. No, but, it's strange. Nagisa is 99.9% sure that he's dealing with the real Korosensei… but eliminating that 0.1% chance is part of being an assassin, he thinks. What it comes back to, more, is Korosensei himself. Nagisa wants to show his sensei that he can be alert and cautious even in a new, foreign environment – that he can use what he's been taught to keep himself honest and safe.
It's all part of his pride as a student of assassination. Nagisa holds the anti-sensei knife out casually, like he has no intention of using it in a thousand years.]
I don't know what way you were thinking of to remind me, but I won't doubt your identity if you can tell me something only Korosensei would know. Not just some test question, something like, mm… ah! After you went to New York to watch the pros, what did you tell Sugino about his body to make him a better baseball player?
[No way an imposter would know an intimate detail like that. And there's also no way that Korosensei would forget.]
