I like this line:
"You're not my assistant. But my partner."
Conan says it to Ai.
Ouh, I'm sorry if I'm out of topic. But I very like this one:
"A secret makes a woman woman"
Sharon tells to Conan.
And I forget what line when conan said to kid. He answered kid when kid said:
"Detective just man who bla bla bla" (forgot v^_^)
And conan answered it, I forget. hehehe
