The Runaways

 refers to an unmarked quest in Fallout 3.

If you engages James Hargrave in Rivet City in conversation and bring up the issue about his equally problematic alcoholic mother, he gets angry. This leads to an option for you to insult and goad James into running away from home (uses Speech skill). If successful this earns you Bad Karma and have repercussions -- Rivet City residents and guards later report that C.J. Young (well-behaved little daughter of the Young family) has gone missing. You receive a note on the PipBoy indicating possible responsibility for C.J. going missing because of the encounter with James.

One of the female Rivet City guards may tell you that she has on several previous occasions seen these two children running across the Rivet City Bridge which connects the ship to the dangerous mainland. You may chance upon this happening if located at Rivet City Bridge in the early morning.

When you find James and C.J. at Anacostia Crossing Station you can bring them back home. If you do so C.J. Young will be able to talk to the player.
