Forum:Could Agatha be Barry's daughter?

Warning: this theory goes well into tinfoil-hat territory. I don't consider the following case persuasive, but it's been gnawing at me for a while and I wanted to see what other folks think of it. You have been warned.

Consider the following:


 * The only known issue of Bill & Lucrezia Heterodyne, Klaus Barry Heterodyne, was confirmed to have been killed when the Other attacked and interred in the family vault. In other words, Agatha is not the "missing child" of Bill & Lucrezia's who disappeared when the Other attacked.


 * According to the cast list, Barry is always paired with "The High Priestess" in travelling Heterodyne shows. However, this character is never given any particular identity of her own.


 * The clothing of the "High Priestess"( 1, 2) looks an awful lot like that worn by Lucrezia in Vrin's flashbacks.


 * Barry is depicted as having fair hair in flashbacks, while Bill is invariably depicted as having dark hair. Agatha, of course, is blonde.


 * While multiple lines of evidence point to Agatha being Lucrezia's daughter (including Lucrezia herself confirming this), Agatha seems to have simply assumed that she was Bill's daughter. Klaus, at least, seems to be open to the possibility of Barry being her father.  Adam and Lilith were conveniently cut off before they revealed Agatha's parentage.

So here's the theory: Agatha is really Barry's daughter, not Bill's.  The "High Priestess" and Lucrezia are one and the same. Rumours of Barry's & Lucrezia's affair must have leaked out over time, but nothing definite was known. After Bill & Barry disappeared, the mythology that developed around them split one character into two -- after all, they were romantic heroes, and it wouldn't do to have them involved in a messy love triangle.

The only reliable witness who claims Bill is Agatha's father, in fact, is Barry himself. The question then becomes why Barry would tell his daughter that he was not her father. He'd have to have some pretty strong psychological motivation to do that; while his state of mind after the attack was unexpected, we don't really know enough about Bill & Barry's relationship or actions after the attack to know what that motivation might have been.

Thoughts?
