'Mind if you lead the way, Mrs. Piper? I'm a bit of a lost puppy here.' You tell her.

'Sure thing, Cods. Hold up a sec, will ya?' Piper walks up to a little girl on the stand.

'Hey Nat, how are you?' Piper asks curiously to the young girl holding newspapers.

'I'm OK, Piper. Thanks for worrying though.' She responds to her.

'That's great. I'll be heading out for a while, OK?'

'Oh, OK...You're going with your pet robot?' Nat jokes.

'Very funny, Nat. Anyway, I gotta go, see ya soon.' Piper walks off and you follow.

Piper lead you arounf the back of the shops. You can see Nick's sign saying in bright, neon pink letters 'Nick Valentine's' with an arrow puncturing a heart. You're more curious than ever to see Nick. As Piper stopped at the door, she insisted to let you in first.

'Codsworth, you can go first.'

'It's OK, Piper, ladies first!' You had a laugh in your voice.

'Oh you-! Fine, I'll go first.' Piper says beaten.

She opens the door and you follow her inside. You see no sign of a man that looks like a detective anywhere.

'Where's Nick?' Piper starts the conversation with a woman looking at the cases.

'He's gone. He went to go look for someone named Darla...hasn't came back.' The woman says.

'Can you tell us more, Ellie? Please? Codsworth needs it.' Piper begs, hoping for more information.

'Nick went on a case to find Darla, who was believed to be kidnapped. He went to some hideout in Parkstreet Station. There is an old Vault they use as a base. I told Nick he's walking into a trap, but he just walked out and smiled like he always does.' Ellie looks at you. 'If you find him, bring him back here, please...'

You look over to your Pip-Boy, seeing that the map has updated, you mark your location and you're ready to set off. You turn one eye to Piper, who was waiting and is looking at you with a smile

'Ready?' You ask Piper.

'Ready. Let's go.'

You exit and head out of the city. This'll be a long journey to find young Shaun. First, you gotta find the detective. After that, you can ask for help, right? Surely, he'll help a desperate robot that's looking for a lost infant...hopefully. Piper follows you from behind, you lead the way to the vault. It was a long trip, but it doesn't really matter. You've encountered some hostiles along the road, nothing's going to stop you from finding someone you love. Once you arrived to the gear-like Vault door, you had bad vibes. You felt most Vaults are just...bad vibes now that you've seen what happened in Vault 111. You had a bad feeling about this, you went on anyway. You access the door with your Pip-Boy and wait for it to open. It takes a minute or so to slide and you enter the vault. Very frightening to be here. Wonder why Nick would come here alone.

You sensed that there was hostiles nearby and switch to your buzzsaw arm. You try to be sneaky as possible to sunrise attack him. Surely your thruster makes noise, but you try anyway. You charge and slice at his neck so he can't warn anyone with his screams. His scream worked anyway...The others were alerted by this and search for you. Oh dear...You decide what's the point anyway and show yourself. Piper, from behind, shoots at them as you melee attack them for now. You decide to switch to your flamethrower and burn them to ashes. Quite brutal of you, but it's for their own good. You see that someone is occupying Nick inside a room, locked up. He's held prisoner...You come from behind the man and stabbed him with the saw. He drops dead and you find that he had dropped something; terminal password. You're not sure if you can use it, but luckily you brought Piper with you.

'Piper, think you can open it?' You day as you hand her the password.

'Piece of cake!'

Piper opens the locked door where Nick was trapped in. You approached him slowly, scanning him. He seems...different from a regular human being. Something about him you can't put your 'finger' on it.

'Ah, my knight in shining armor. But the question is, why does he come all this way, risk the life and limb, for an old private eye?' Nick tells you.

'Young Shaun is missing. He was kidnapped, but I don't know who took him, or where they went.' You reply.

'A missing child, huh? Well, you came to the right man. If not the right place. I've been cooped up in here for weeks. Turns out the runaway daughter I came here to find wasn't kidnapped. She's Skinny Malone's new flame, and she's got a mean streak. Anyway, you got troubles, and I'm glad to help. But now ain't the time. Let's blow this joint. Then we'll talk.'

Nick leads you and Piper to the exit, but there's trouble...

'You come into my house, shoot up my guys! You have any idea how much this is gonna set me back?!' Some man in a tuxedo and top hat says. He's holding a gun with some guys behind him. A woman stands beside him who you assume is Darla.

'I wouldn't be here if it weren't for your two-timing game, Skinny. You 'ought to tell her to ride home more often.' Nick states.

'Aww, poor little Valentine! Ashamed you got beat up by a girl? I'll just run back home to dad, shall I?' Darla says sounding like one of those evil movie characters.

'Should've left her alone, Nicky. This ain't the old neighborhood, in this vault, I'm king of the castle, you hear me? And I ain't gonna let some private dick shut us down now that I have a good thing going.' Skinny said.

'I told you we could've just KILLED him! But then, you had to get all sentimental. All that stupid crap about the old times.'

'Darla, I'm handling this! Skinny Malone's always got things under control.'

'Oh yeah, then what's this robot doing here, huh? Valentine must have brought him here to rub us all out!' Darla IS what Nick had said after all...

'What's the deal with you people and Nick anyway?' You say.

'Darla's a runaway. Her father wanted me to bring her back home. Turns out she skipped town to be with my old pal, Skinny Malone. Mob boss...Never thought he'd manage to scrape together a big enough crew to take over a Vault. Guess life's full of surprises.

'Hey, who's running this show, here? You got something to say, say it to me.' Skinny asks you.

'You and Nick know eachother?'

'Yes, Enemies are kind of the closest thing you get as friends in these parts. Now quit stallin'. You gonna talk? Talk.'

'This is all just a misunderstanding, Skinny. You know that. You let us walk and we won't come back.' You convince him.

'You and Nick killed all of my crew and you expect to just...Arg! All right, you're lucky I still owe him for that time back in the Quarry!'

You and the others leave immediately...You head back to Diamond City with Nick and Piper...
