Quote lestress: Do you mean that Brad's mother doesn't exist and never did or that she isn't really Brad's mother? I am confused.
No...just that he could not possibly have known where his mother was every minute of the day. He may have checked in every few days, but not every minute of the day. Can you imagine how suffocating that would be? He had to give her some breathing room. Unless, of course he has a GPS unit attached to his mother so he can track her, I don't think that it was possible.
But as mentioned before.. One of his wives would have caught on and asked who he was talking to in Italy ALL the time..
