The city is a mess again. People cheer. Hal, depowered but free, sits on a curb. Megamind offers him a hand. "You're not a hero. You're not a villain. You're just Hal. That’s harder than both." Hal scoffs, but he takes the hand.
Roxanne finds Megamind hiding in an abandoned Metro Man museum. She tells him, "You beat Titan because you understood a villain's ego. You don't understand a hero's sacrifice. Metro Man didn't win because he was stronger. He won because he knew when to lose." Megamind snaps: "I never lose! That's my thing!"
Megamind realizes The Sanitizer absorbs focused energy but not diffuse emotional energy. He needs someone who generates raw, unfocused, chaotic power. Someone like… Tighten (Hal Stewart). Hal is in a low-security rehabilitation center, now obese, depressed, and watching Megamind’s hero montages with bitter tears. He lost Roxanne, his "powers" (they’ve atrophied from lack of use), and his dignity.
