Nolan: Every bait and tackle needs a website, brother.
Nolan's "Jack and Emily sitting in a tree" in the fourth episode.
Nolan's call to Emily in the same episode:
"Your fake boyfriend is getting wasted in your other boyfriend's bar. Come and join the fun. Testosterone is on the house."
Nolan waking Emily up from a bad dream, only for her to grab his throat out of reflex.
Scrawny little Declan (complete with oddly poofed hair), coming over to his brother at the bar and saying nervously "Jack, see that guy over there? His name's Bull and he wants the bartending gig. Scares the hell out of me." (To elaborate - Bull stands about 6'4, and Declan's 5'6.)
Victoria walking in on Declan in his underwear. And then:

Dr. Banks: I've just finished your book on the D.C. Sniper. Do you want to know what I think?
Mason: Not really, but don't let that stop you. Let's talk about your new book on attachment theory instead; I've just read it.
Dr. Banks: Really?
Nolan's disguise as "Burt the cable guy" complete with fake mustache, which he uses to get into the home of the mysterious white haired man who killed David Clarke and plant a camera.
Mason being a snarky bastard towards Victoria in Forgiveness.
Mason: Do you gag a little when you say that? "Honestly?"
Conrad blustering that his portrait hasn't captured the "depth" of his eyes, and informs the painter thusly: "Arctic pools! Arctic pools, remember."
Conrad gives Daniel advice on cheating on Emily:
"If you get bored, you know, switch paramours, not wives. For one thing, it's far more cost effective. I mean, not that affairs are cheap..."
