Stages of "Unlikely Valentine" quest
1. Find Nick Valentine
Nick Valentine apparently went missing while investigating a case. If I want his help in locating Shaun, I'll need to find him first. His last known location was Park Street Station.
The entrance to the Park Street Station.
Follow the tunnels until you reach the big Vault 114 door, open it.
Nick is held in the overseer's office in the main section of the vault. You have to kill the boss - Dino and loot Overseer Door Password from his body.
2. Free Nick Valentine
I've found Nick Valentine, but he's being held prisoner by some thugs in Park Street Station. I need to get him out of there.
Use the terminal next to the locked doors.
3. Talk to Nick Valentine
Explain Nick, why you are here. There is Speech Bobblehead on the overseer's desk, grab it.
4. Follow Nick Valentine
I've freed Nick Valentine and filled him in on my situation. He'll help me find Shaun, but first we need to get out of this station.
Follow him. Nick will open all doors, etc. There is Astoundingly Awesome Tales magazine in one of the corridors.
Skinny Malone and Darla will be waiting for you in the last room.
If you manage to convince Darla to leave Malone, then you can leave this place without a fight. Otherwise you have to kill them all.
Follow Nick to the exit.
5. Quest completed
I've rescued Nick Valentine and we've escaped from Park Street Station. Now he's free to help me find Shaun.
