Flash (Fallout 3)

Flash is one of the citizens of Big Town. He asks the Lone Wanderer to go alleviate the hostage crisis, which sends him or her to the Germantown police station. He continually boasts about his special weapon, although it is not unique, and just a standard .32 Pistol

If you threaten him he'll say "Hey buddy, suck my brahmin meat. We're all super mutants here." If you continue threatening him he'll say "Hey, take it easy, I was only joking. None of us have any real experience with guns."

Also when you first talk to him when starting the quest "big trouble in big town" there is a choice where you can kill him beware if you choose this the whole town will become hostel towards you.
