It wasn't normal for people to be watched by angels, But John was. You were that angel. He didn't know why he was being watched by you, he's an outlaw.

"Ain't ever thought of me bein' a bad person?" John would ask, Rummaging through his wardrobe to find his bandolier.

He was planning on robbing a stagecoach, Of course you would accompany him since you never really left his side.

He was pretty tired of being followed constantly, though. Always complaining about it one way or another.
