Both Sci-Twi and Professor Gadd were running tests on Danny as you brought him home. 

Danny: Seriously, this is where you live? 

(Y/N): Yeah, got it from capturing some ghosts. 

Danny: And you capture them through that vacuum? 

(Y/N): It's the Poltergust, thank you very much. Doesn't your family have weird contraptions? 

Danny: Well ... 

He began to remember a lot of what his parents would do. 

Danny: Yeah, that's kind of right on the money. 

Professor Gadd: Criminy, he really is half ghost! 

Sci-Twi: How fascinating. Hmm ... 

She got out a needle. 

Danny: HEY! HEY! Careful where you stick that. 

Sci-Twi: This is in the name of science, it won't hurt a bit. 

Danny: NOOOOOOOOOOOOOOOOOOOOOO! 

You grabbed him. 

(Y/N): Come on, Danny, just take it like a man. 

Danny: NO! I- 

He didn't feel a thing. 

Danny: How did that happen? 

Sci-Twi: I'm just that good at extracting. 

Danny: Geez. 

At that moment, some blue ghost-like essence came from Danny's mouth. 

(Y/N): Wh-What was that? 

Danny: That's ghost sense, it lets me know when a ghost is nearby. 

(Y/N): Are you kidding me? I've got the two closest ones here inside of the Poltergust. 

Technus: ACHOO! It's really cramped in here! 

Box Ghost: Come on, guys! Let us out of here! 

(Y/N): Would you both just shut up?! 

Danny: No, it's not like that. There would have to be a- 

Suddenly, the wall burst down. 

???: It took me forever to find this place, but I've got you now, Ghost Boy! 

Skulker was standing right there in the hole in the wall. 

(Y/N): What is it with you guys and breaking down walls? 

Danny: Skulker, so you got any new upgrades to your suit or something? 

Skulker: Hey, you noticed. That actually makes me- ARGH! Nevermind! I'll rip you to pieces and- 

He got contacted at that moment. 

Skulker: Wait a second. 

He started talking through his wrist communicator. 

Skulker: WHAT?! Oh come on! I came all this way to- FINE! FINE! OKAY! 

He hung up. 

Skulker: Looks like I must postpone our fight for much later, Ghost Boy. I released a bunch of ghosts over the city. Let's see if you can catch them all. I'll be waiting for your results. 

(Y/N): You're on, tough guy! 

Skulker takes off. 

(Y/N): Looks like we got work to do. 

Danny: Yeah, going ghost! 

He goes into his ghost form. 

(Y/N): Let's assemble our team and get going then! 

Much, much later... 

You, Danny, Team RWBY, and Sci-Twi had arrived at Danny's home of Amity Park, which happened to be located in Vale. 

???: Danny, there you are, where have you been? 

???2: I thought my phone wasn't working there for a second. 

Sam Manson (One of Danny's best friends! She's a goth girl and ultra-recyclo vegan! Unlike most goths, she's not cynical or stoic! She is rather friendly, strongwilled, independent, and outspoken! Her choices come from the fact she rebels against her rich parents! Voiced by Grey Delisle!) 

Tucker Foley (One of Danny's best friends! He is an expert on all forms of technology! Unlike the more level-headed Sam, he's super chatty and doesn't know when to shut up! He's also a massive womanizer, with most of his attempts to ask a girl out falling flat on his face! Voiced by Ricky Collins!) 

Danny: We don't have time to discuss these guys. Skulker's causing trouble, and who knows how many ghosts he's set loose. 

(Y/N): And we're here to help. 

Ruby: Hi! 

Sci-Twi: Friends of Danny? 

Sam: Yeah, pretty much. 

Tucker: Hello ladies, I'm Tucker. Don't let the red cap, and glasses fool you, I'm- 

Weiss: Yeah, no thanks, we're already taken. 

Tucker: Eh, it was worth a shot. 

(Y/N): Okay then, so where exactly is your house, then, Danny? 

Danny: Just follow me!
