So who actually believes this theory along with the other conspiracy theories, bloodlines, Phoenicians, decendents of various historical figures, etc., that Sadie has been typing on for some time ?
After all, they are part of her theories as to why Madeleine disappeared.
Meanwhile, this Watcher, has this person been proven to exist ?
...and I almost forgot, the high level conspiracy claimed by Sadie in one of her theories protecting the 'abductor'.
What nonsense! Bloodlines are not theories. They are very much a fact.
Quite a put down in my neck of the woods dependent on the tone of voice used in delivery is: "Ah kent his faither!"
Bloodlines are interwoven into the fabric of our society; if not, why is it a descendent of the House of Saxe-Coburg-Gotha who is entitled to bear the Royal Coat of Arms and to sit on the throne of Britain but you or I are not?
As I see it, the difficulty you have with Sadie's theory is that there is nothing about it that is impossible. It doesn't matter that you may deride 'bloodlines'. Quite patently there are those who do not ... else no "Vivat Regina!".
We could have been closer to identifying a watcher in the balcony opposite, had the Portuguese police bothered to pick up the ends of the cigarettes which had been smoked there.
In my opinion you cannot retain credibility by dismissing out of hand one "high level conspiracy claimed" while adhering to another "high level conspiracy claimed".
From the paucity of your argument, I think you have a very long way to go if you wish to make a dent in Sadie's theory ... you have failed miserably so far for the reasons I have enumerated in my previous post.
