Chloe: Lex, I thought you'd be sharpening your shears behind bars by now.
Lex: Someone else confessed.
Chloe: Once again a Luthor snake manages to slither away from the grip of justice.
And later. . .
Lex: Tell me, Chloe. Tell me everything you know.
Chloe: Here's everything I know, Lex. You need some serious psychiatry.
Clark: I'm not going to let you kill anyone else.
Kara: I haven't killed anyone. Not yet, but you're starting to tempt me.
Clark: Uh, listen, when I talked about fitting in, I was thinking of something with more clothes. Th-this is definitely not blending in.
Kara: You mean undercover.
Clark: Yes, exactly, and this is . . . not covered.
Chloe: Isis seemed to make a lot of sense when I thought you were just out to help people. In textbook talk Isis is the goddess of love, and life, and healing. She even marched to the ends of the earth to help jumpstart the man she loved. I want Clark to have that kind of loyalty in his life but I'm just not sure it's from you.
Lana: I would do anything for Clark.
Chloe: Even kill. What a lucky guy. What the textbook left out is that Isis is also the goddess of the underworld. She's responsible for bringing the great god Rha to his knees.
Lana: You believe that I would do that to Clark.
Chloe: Not intentionally. But I realize now that you're capable of it. You should just know that I'm not gonna let that happen.
And my all-time favorite is too long to type but it's from season 6 Hydro. Chloe figures out that Clark was hiding GreenArrow's secret and that he kissed Lois to cover it up. Chloe uses Lois to just totally torment him, the actors' performances make it hilarious!
