Shouldn't you be... more or less prepared to die in a fire or some such, for the sake of your country?

The past days he's stuck to his job - his real one and his make-believe - gathering enough evidence to have the maid arrested on charges of attempted homicide. All the while, John's words have resonated within him. Sentiment. It's all been a bit distracting.
