I am sitting on the pew, and practically all of Rivet City is here with me. It was too hard to resist, I blew Father Clifford's head off with my .44, and proceeded to shoot everyone else with the .44.
After everyone was dead, I devoured Hargrave's mother in front of him and that girl CJ. Half the city was on fire, blood was all over the walls, it felt like the good old days.
Maybe when I am sure I have no more use for Fawkes I will come back and kill them all for real.
