Well, given the content of the last video I found, I've decided to use the maps I posted in Switch to find the locations in Target and go to the lake house myself.
It seems clear, to me at least, that Mark has been ArthurMan all along. It also seems clear that he's been holding Emily prisoner in the lake house since at least July, either before or after he sent Harrison, Dicky and Joe to their deaths.
I don't know who he attacked in the video I posted in Hope but that coupled with the content of Open has led me to believe that he's extremely dangerous.
I'm going to pack now and leave tomorrow.
I can only hope that I'm not too late.
