Here's how talking to Blackie and getting answers in The Silver Streak and Daylight Special.
[the group sooon arrive in the dinning car]
Blackie: Ah, there you guys are.
Nyx: Oh, hey Blackie.
Blackie: I asked you guys if you could join me for breakfast, but it's now lunchtime. What happened back there?
Skyla: Oh, we sort of fell behind.
Blackie: Is that so? Well, how about you join me now?
Minka Mark: Alright, besides I'm feeling hungry anyway. [grabs a banana, peels it, and then starts eating it]
Nyx: I guess we can stay. And grab a quick bite to eat.
Skyla: I guess, too.
[they take a seat]
[a little bit later, the group is finishing their food, then as Penny Ling grabs an apple and is about to eat it, she sees something (or more appropreitly: someone)]
Penny Ling: Guys, I think you should look at the last table.
Zoe Trent: What do you mean?
Penny Ling: Look who's there.
[We see the Dazzlings]
Sunil Nevla: Oh no, it is the Dazzlings!
Blackie: [takes a look after taking a quick drink from his coffee] So these 3 are the Dazzlings?
Skyla: They're also the Sirens. Brian hates them, and they feed off negative energy.
Blackie: I know. Spongebob made them sound different in his letters to me.
Nyx: Wonder what they're up to.
Russel Ferguson: I bet they have something to do with what Skyla saw last night.
Skyla: I guess you're right.
Zeñorita: I say we go check it out.
[they get up and follow the 3 girls]
[the 3 girls don't notice the group following them]
Adagio Dazzling: Come on, come on.
[they head inside a coach suite]
Skyla: Why are they going in there?
Pepper Clark: It might be their coach suite.
Nyx: Let's ask those sirens a few questions.
[they head up to the Dazzlings' suite]
Aria Blaze: [inside] The sooner we get this done, the better.
Nyx: [knocks the door]
Sonata Dusk: [opens the door] Yes?
Nyx: We wanna ask you a few questions.
Sonata Dusk: Just a minute. [closes door]
[we hear chatter inside the suite]
Adagio Dazzling: [inside] Let them in.
Sonata Dusk: [opens door] Come in.
[they head inside and take a seat]
Adagio Dazzling: So, what is it you wanna ask us?
Aria Blaze: How our singing is so cool?
Aria Blaze: What are you doing here you little twerps?
Nyx: We just wanna know what Sunset was searching for in one of the suites of the Silver Streak.
Adagio Dazzling: Oh, she was trying to help a close friend of ours, Professor Gold Rush.
Snowdrop: Professor Gold Rush?
Aria Blaze: Yeah, he wanted to show us some interesting gold he found, but he cou;dn't find the papers that told him where the location of it was on the trains.
Nyx: How can we believe you aren't lying?
Sonata Dusk: Here's the Professor's book about his findings.
Skyla: [reconizes the picture] It's him!
Nyx: What's him?
Skyla: The man I saw.
Sonata Dusk: What are you talking about?
Skyla: Last night, while we were getting ready for bed, I saw a dead man fall of the Silver Streak.
Adagio Dazzling: And, you're saying he looked like the professor?
[then a man that looks like the Professor comes in]
Professor: Hello girls.
Adagio Dazzling: Ah, Professor.
Skyla: [in her mind] "But... he's dead!"
Professor: Who are they?
Aria Blaze: A couple of pests.
Sonata Dusk: No, just a couple foals and their friends. We were just sharing about that gold you wanted to show us.
Professor: I see. I suppose I'm to blame for the confusion since I misplaced my location papers.
Adagio Dazzling: Yeah.
Professor: Anyway, I think I'll go get a drink and lie down. Anyway, It was nice to meet you foals, I hope this trip will be just fine the rest of the way. [leaves]
Skyla: I guess I made a mistake.
Aria Blaze: Don't be silly.
Skyla: No, really. I've stuck my muzzle into stuff that's none of my buisness all based upon a dream I had. I guess I was dreaming.
Nyx: it's fine. We'll be going now.
Snowdrop: Sorry for the confusion.
Sonata Dusk: No trouble at all.
[they leave the compartment]
Adagio Dazzling: See, I told ya they'd fall for it.
Aria Blaze: Easy for you to say.
