Did Harry inadvertently kill Early?
After Harry finds the bomb and goes to call Early, it seems like Early is headed straight to his apartment until he hears the phone from outside and pauses, then turns to go to his mailbox.
Had the phone not made him pause, do you think he would he have just gone straight to his apartment? Thus making Harry's call actually have the reverse effect. Just a thought.
Or was this just bad editing, and he didn't hear the phone and just turned around on his own.
