Something that has always confused me about the connection between Blaine and Charlie The Choo Choo, I assumed the women who wrote the book maybe had some knowledge of Blaine, and is implied she wrote the book to warn the Ka Tet, but when Jake see's Charlie in Topeka, why does it flash its light at him? was it Jakes Imagination or was Charlie in that version of Topeka Blaine in another form?
