Detailed walkthrough

 * 1) Upon completing Tradecraft, speak with Carrington and give him the prototype; he'll ask you to go to Old Man Stockton to assist with the newest synth he's rescued.
 * 2) Head to Bunker Hill and speak with Stockton -- he's the well-dressed man in the main building.  He'll respond to the security phrase with the information that there're raiders at the drop-off location and ask that the raiders be removed.  The standard persuasion check to get more money is available.
 * 3) Head to the church that's indicated by the quest marker and kill the raiders, then wait until it's dark out.
 * 4) Stockton will bring the synth in, light the lamp, and then leave.  You can talk to the synth, but he doesn't know much.
 * 5) In a couple of moments, High Rise will arrive and ask for help with the next stage of the railroad.  Agree and follow him along.  A couple of raider groups later, you'll reach "Ticon", which you will then be allowed to use as a safehouse.
 * 6) Return to Carrington to get your reward and next mission.
