I don’t need saving... and I am done fighting demons.

Snart

Constantine

You cannot save this one, Constantine.

Mallus

Sara: I'm looking for the doctor. He's not at the institute.
Cyrus: No, ma'am. He's off in one of his trances.

Moore: Up high, he can act with the confidence of the devil himself.
Marcus: Not the devil. God himself.

Kreizler: I'm here today as your pupil, madam.

Connor [to Roosevelt]

Chasing clues will mean he's always a step ahead of us. We must see what's behind the clues.

Kreizler [to Moore]

You'd best not let Roosevelt catch you drinking your lunch. He'll have your badge. Pious prick!

Byrnes [to Connor]
