Skipped mess hall key, Fillmore dialog skipping

I was able to skip finding the mess hall key by using the claymore. My method was I smashed the barrels inside of the mess hall through the wall and when one guard got close to investigate I hit him, which aggroed the other two and him to the door where I could kill them, once they were all dead the door popped open and I could proceed. When I talked to Fillmore afterward his dialog kept being skipped (every other line or so) with no input from me.
