Okay so hear me out yet again

If a crocodile takes your kid and says “I’ll only return it if and only if you guess correctly what I’m going to do next” what would you say?

Technically if you said “you’re going to return my kid” and it’s correct then you’d get the kid back. But if you say “you’re going to take my kid” and that’s what the crocodile was planning on doing then you’d get your kid back because technically you guessed correctly… But like if you tell the crocodile the same thing and that’s not what it was going to do it would still give back the kid because he had no intention of keeping your kid…
