I'm also confused by this, is he was referring to child.?
I always take the translations with a pinch of salt, especially as we haven't got the original text to check against. Truth is it may not actually say that at all lol it depends how the translator read it in this context. (There are plenty of translation errors in past scanlations for example that totally change the meaning of a sentence etc) Anyone out there got access to the raw???
I remember Takaba tried to make Asami surrender in another chap. with handcuffing him to the bed. Perhaps Takaba thought the baby things would weaken him.
