Reginald is talking about his life before he was a ghoul. 

I used to be a scout long ago. my job was to seek towns across America and make trade deals with the local farmers and settlers. the plan was to establish new relationships and allies. we were so tired of fighting the brotherhood after the war. all we wanted was rest and start anew we had no HQ are leader was dead most of our man had been gunned down by some kid and his dog. so what was the point of using our greatest weapon with no guidance or manpower? so we did the logical thing. we surrender. * scoff* some good that did, you guys didn't care you killed us anyway, unarmed prisoners of war shot down like dogs. you took our weapons, our tech, our lives and turn me into this when you blew up the last home I'll ever know. tell me, what did you do with all that knowledge and power you gained after? you tell me you tried to help the waste but all I've heard was infighting and members of your factions splitting off calling themselves Outcast. what a joke. that's the thing about you guys you collect all this shit but you have to no goal in mind you have no future or any vision. you guys are nothing more than a dead-end.
