I couldn't get the Kidnapping Mechanism
I don't quite understand here: How did the kidnapping start? Did David's mother purposely arrange for Max to kidnap her own kid, and upon doing so, pay him to kill David? If this is the case, it doesn't make any sense because of the chicken-and-egg cycle. For e.g.,
1. If it was David's mum who orchestrated the kidnap, why did she bother to call the police?
2. Wouldn't Max be puzzled to visualise that his target child is actually David's mum (who called him to kidnap David), when he was dressing up as Santa Claus giving out presents to the kids at the party)?
3. There was a scene that showed Max calling David's mum while the police was trying to trace the call. What's the purpose of this scene when David' mum simply want David dead?
