What about the possibility of Gillian to hide her relationship with David? Or maybe because something was happening to them or around them and they needed to really go dark to the fans?

So far, this is the one denial theory that makes the more sense to me and the one I like the most. I do want to believe that! It’s irrational and crazy and conspirationist (not sure it’s a word, but you get me, right?) but it sounds plausible to the irrational crazy and conspirationist (still not a word, right?)’s part of my brain.
