Eddie Brock: It's Brock, sir. Edward Brock Jr. I come before you today, humbled and humiliated, to ask you for just one thing. I want you to kill Peter Parker.
Mary Jane Watson: What's happened to you?
Peter Parker: I don't know. But I have to stop it.
Harry: Looks like I came just in time.
Spider-man: Yeah, few seconds ago wouldn't have been so bad either.
Eddie Brock: My spider-sense is tingling, if you know what I'm talking about.
Eddie Brock: I like being bad, it makes me happy.
Venom: Never wound what you can't kill.
Chosen answer: Answered in the comics: Peter's Spider-Sense tells him if someone is looking when he's about to enter/exit the apartment as Spider-Man.
