The vagrant is an old, and apparently homeless, man who lives in Freeside. This non-player character seems to be pretty much useless like the Destitute traveler. Other then that not much is know about him.
I Could Make You Care: When player needs to ask around Freeside about a rangefinder, dialogue with him is possible. The player can pay him for the information, threaten him (Strength 7 needed) or if the character has low Intelligence there is special dialogue line which makes him talk like an intellectual and bright person (similarly to Torr from Fallout 2).
pc Sometimes, if the player kills the vagrant, you will hear quotes like "Are you crazy man, I've got two kids to feed!" or, "Help!", similar to when your reputation in Freeside is lower than neutral, and Freeside thugs try to mug you but flee. [verified]
