With buying myself a Kindle end of last year I finally convinced myself to take the plain text scripts of NXE and convert them into PDF, so that your text markups for computer text, shouting etc. would look a bit better. Works going fine, I'm almost done with Revelations in Real Time...

But in chapter 7, "The Third Child", DJ says something that I do not understand in the context. Someone thanked him very politely using Japanese and he answers with "Ist nicht."

That would be something like "is not" in English - as a native German speaker I just do not see the sense in that? It makes neither sense in the context nor as a standalone sentence. Seems to be the first bit in all of NXE that eludes my understanding

Can someone try to explain what was meant by that?

Sincerely,
Eochaid
