Tread Lightly

Tread lightly.

About this quote

Walt delivers this two-word warning in Season 5, Episode 9 ("Blood Money") of Breaking Bad, created by Vince Gilligan. After his brother-in-law Hank (Dean Norris) confronts him about being Heisenberg, Walt — rather than capitulating — calmly threatens Hank to back off. The laconic menace of the line marked a significant escalation in the final season's cat-and-mouse dynamic.
