"I take back every bit of energy I gave you. You're nothing! You're shit." Best ending ever! Or, at least it was until Executive Meddling completely ruined it two minutes later.
"I'm into survival." Perfectly sums up Nancy's character. It's no wonder that despite appearing only one other time canonically (not counting the metafictional New Nightmare, which is partially a tribute to her actress Heather Langenkamp), people tend to consider her the protagonist of the entire series.
