I am asking about the sentence this guy (James Wilson, House's best friend) says at 7:00 in this video. The transcription is:
Okay, maybe. But he's our friend and this is his one chance to not be miserable.
I am curious about the ''one chance''. Does one chance work as only chance? Or should I wrote his one-chance?
Still, the biggest question is about the to not be. As far as I know, it is not to. For instance, tend not to, try not to, etc. or also in reported speech: they told us not to. Is it wrong what he says then, or is this situation different from the ones I have cited?
PS: The video corresponds to Chapter 16, Season 5, The Softer Side, as you can see in its description.
