who were the THEY Mary spoke of
she said in something BC(do not remember the date) we were at our house and they came after me. you protected me and they stabbed you
in something AD they burnt down our house and you pulled me out of the fire. john said and 60 years ago?
she replied we were coming out of a new movie"john replied Frankenstein" and mary said they beat you so bad. they would not even let me ride in the ambulance with you. when i got to the hospital you did not remember me so i left.
this implies that there is some organization that has been after them for thousands of years trying to end them.
and the way the bad guy Red was speaking to him implied he knew exactly what hancock and mary are . with his speaking of" you have had a good run, its time to move on etc etc"
so i ask Who are They
