The 'Hoodie' is... another survivor from the 2nd Tower!!! Hey, does anyone remember what the name of the woman who was in charge of that group? The one who was supposedly a master planner or tactician? I remember hearing it somewhere, and was wondering when / if she would make an entrance into the story. Maybe now?
More evidence that it wasn't
the Mallers was the location--yep, I also went to Google maps, and saw how close 8th + Grand is to the original Tower. Seems very un-Maller like, especially since they were all going south. Besides, when these trees were planted, the Mallers would have been having a field day pillaging the city. Not like them to think ahead to this degree.
So how did Hoodie sneak up unnoticed?
SUBWAY THEORY
The hidden group has gone underground--literally--and is making use of underground subway tunnels to travel unnoticed.
