One more observation/speculation...again, I'm basing this off the assumption that GH's latest video is accurate, but if BG is not yet on the bridge when Liberty stopped and turned around to take Abigail's picture, then I assume they were "goofing off" or "dilly dallying", IOW taking their time across the bridge. If they also did the same on the trail leading to the bridge, that could account for why it took them ~ an hour to get to the point where the picture was taken. Adults tend to walk trails with more "purpose", and thus don't stop as often to talk, take pictures, maybe sit down and have a "heart to heart", as girls in their age group often do. I won't go down the "catfished" or "met a boy" scenario unless LE states it as a fact, so I'm working with what we have, in terms of accounting for the unusual amount of time it seemed to take for them to get from point A(which we aren't even sure of AFAIK?) and the photo of Abigail at 2:07pm.
