"Lede" is an alternative spelling of lead, the introductory portion of a news story. To "bury the lede" is newspaper jargon for beginning a story without mentioning the critical attention-getting facts.
Fusco refers to John by his first name, and not by nickname as in many other episodes.
John's sniper rifle is for right-handed shooters, although he is left-handed.
A quick sequence of surveillance videos around 35:40 includes several interesting marks made by the Machine.
A red cube around top floors of a building labelled "NSA DSF 203 F12", short for "National Security Agency Defense Services Facility 203.F12". This mark recurs eight episodes later, in “Dead Reckoning”.
A red "restricted air space" circle around the Freedom Tower.
Saturn and Earth's Moon are marked with astronomical symbols. The moon includes a dotted line marking its orbital path. This is possibly the first time we see The Machine mark non-terrestrial objects during the series.
. . . ok, well, there's a rumor about this guy; the police just call him 'the man in the suit'. No one's seen his face; no one knows his name. I'm not even sure he exists, but he's like something out of a comic book. When people are in trouble, he comes out of nowhere. He always seems to be there just in time. And, whoever he is, he saves a lot of lives. And he shoots a lot of knee caps." (Maxine to Reese)
"No bodies, no bullets. So this is what a normal date with you is like." (Reese)
"No, you were right, [the man in the suit is just] urban legend. And with the week I just had, if there really was a man like that, I think I'd have met him by now." (Maxine)
"Mr. Reese, this may not be over. I don't think we got the right guy. The head of HR is brilliant, not the type to hire a pair of washed-up feds to gun down a reporter. And Walker, I'm not convinced he has the cunning or the connections to mastermind something this complicated." (Finch)
"Wait... you're trying to get me a date with her [Maxine Angelis]" (Reese to Finch)
"It was a pleasure meeting you, but it's a shame we never met." (Zoe to Maxine)
