I was just following some Brother hood outcasts (waiting for them to die in combat so I can take get their stuff) when I come across Shrapnel from Rivet city. It looks like he's heading back to Rivet city, and he hasn't been their for a while now (ever since I enslaved Flak). Also he won't die in combat, only get knocked unconscious.
Has any one else found him in the wasteland?
Dose he follow Flak to Paradise falls?
Dose he return to the City?
I just thought it was a bit strange...

Yeah there is a bug in the game that makes Shrapnel follow Flak to Paradise Falls, it'll become part of his daily routine to go to Paradise Falls, because him and Flak have a thing

Can you free people you have enslaved?
