You catch a fish once and it gets away, it’s a lot harder to catch again. (Will Graham, Hannibal S02E04, Takiawase)

Will: Your father taught you how to hunt, I am going to teach you how to fish.
Abigail: Same thing, isn’t it? One you stalk, the other you lure.
Will: One you catch, the other you shoot.
Abigail: What are you trying to catch?
Will: The one that caught you.
Abigail: The one that got away.
