Just hearsay, but I heard Walter never filed the marriage papers. He informed her of that at a group dinner, after they'd been "married" for quite awhile and he was tired of her. Ya marries a sociopath and ya takes yer chances.
That rings a bell for me too.
I vaguely remember one of the female staff telling me that Devon confided that she was not happy with Alan because of his sexual abuse. So, the news was probably a relief to her.
Honestly, I figured something was fishy at the time. But I didn't care either way. As a group, we had already agreed that we weren't subject to WOG considerations. Conventional morals weren't considered to matter much, unless you needed a reason to nail someone for something - then it all mattered. Everyone considered themselves to be "free" of standard social agreements.
Remember, "Goodness and badness, beautifulness and ugliness, are alike considerations and have no other basis than opinion."
LRH admired Aleister Crowley, who is known for saying, "Do what thou wilt shall be the whole of the law."
Alan Walter was definitely in agreement with those as guiding principles.
