I told you to go right

"Well then, I'm hoping she told you the truth about it." Spitfire snorted, reclining in her chair as the music played around us. It was a Sunday night thing, apparently, to have an evening that felt quite a bit like a 1950's bar party. Being one of the most influential, and rich, clans in Equestria, they had spent the money to have an oak stage, drinks bar, and small restaurant over several rooms, all high in the luxury department.
"Yes, I know for a fact that monarchs lie to assassins." Slide-Back grunted, popping his beer open and chugging from it as he leaned on the bar. "I've been lied to, I killed the liar. Simple as."
"Agreed." Fleur added. She shuffled up, and sat with her forelegs crossed as she leaned on the table. "This is a trap, at least we all know how to escape a situation of this calibre."
"I don't." I muttered. "That, and I don't think that we'd blend in that well if we all trotted into Equestria's capital carrying rifles, pistols, and flamethrowers. Unless, of course, this clan now has some hidden train system that goes directly under Canterlot and into the palace." Fleur giggled, and tapped her chin.
"Well..."
"No, don't even." I groaned. "Seriously though. Do you need me to ask how we'll conceal ourselves from Changelings that are roaming the streets in disguise? Do you? No."
"Why not just ask the Princess?" Spitfire shrugged, lowering her aviators slightly. "She'll probably tell ya."
"Well, it's worth a shot, if she isn't lying to us anyway." I replied. "Lemme get to someplace quiet, then I'll give it a shot." Just as I stood to leave, a hoof shot up and grabbed my shoulder. The owner was none other than Six, smirking at me.
"Come oooooooon." she laughed. "Party just started, and I'm drunk already! Stay for a while?" I looked at her with no emotion.
"Nah." I replied, brushing her hoof off. "Just try not to burst into the dorm with some other stallion, alright? I can't deal with that noise."
"Awwww...ok..." Six slurred, before turning around to go bug somepony else in her stupor. I gave the others a nod, wished them well and good luck with the drunkards, before retiring to my quarters. The only thought in my mind as I left the hall and began to head up the stairs was 'is this really my crowd'?

Yes.

Luluuuuuuu!
Thunder? Still awake at this hour?
That's what she said. Anyway, I have a question.
Is it about you and your little clan?
Yes. Ok, right. So, you're aware of how being an assassin works?
Sneak in, conceal weapons, plan escape, kill target, escape, receive money, buy more weapons?
Exactly. But the thing is, I doubt we can conceal thousands of guns and fire spewing weapons from public eyes and disguised Changelings.
Hmm...go on...
Well, that's our problem. Hundreds of ponies exiting a train carrying weapons is hardly going to get past security, Changeling spies, and Blueblood's dickface patrol. Is there anything you can do? Hidden trains, perhaps? Airships? I don't know?
Well, I suppose that's true. Let me think about it for a while.
Alri-
IDEAAAAAA!~~
That was fast. It's why I love that adorable little brain of yours.
<3
D'awwwww!
Anyway, I think there's the old miners' train down in the caverns under Canterlot. I suppose we could get that one fired up for your group to use. All you'd need to do would be to find that elevator you used months ago.
You know about that?
Of course I do, sweetheart. It's how you avoided an entire village and almost had your side ripped open from acid. Oh, if that happens at the wedding again, I get to preen your wings.
Ahhh, that'll be...sensual. I'd return the favour, even if it doesn't happen to you.
OK, OK, off topic. So, I'll get my Engineers to invent a combustible lemon that BURNS YOUR HOUSE DOWN get the old coal train working again. It goes at quite a pace, if I remember correctly from my visits there a thousand years ago.
Trains are that old?
Yep; the ones you ride for transport are simply renovated and maintained trains that are hundreds of years old. Real trains go damned fast. Well, off-topic AGAIN. This long-distance relationship thing works well for us, because we can read minds. Well, I can enter yours, cause you massive pleasure or pain, mess with your feelings, and if your brain wasn't so confusing to navigate, I could practically control you.
Comes with being a bloody psychopath: labyrinth mind and randomised thoughts. I think I would have been holding out quite well now if I hadn't have divided 100 by 6 on the 10th or 15th day.
That's easy, it's-
Don't even. So anyway, you're sending the train down which tracks to Crowme?
South side of the city, there should be some tunnels that head off in a perfectly straight line. Get your new friends to wait there, and I can get Engi to erect a teleporter drive the train down there to pick you up. Once you're inside the castle, remember to knock before lifting the floor panel. I think my sister and your friend Ebony are dealing with press.
OK, good, we can deal with accomodation later. But for now, thanks: I owe you...?
Do you even need to ask? Massage, if you would.
Of course, how could I forget my marefriend's biggest turn-on?
It was good speaking to you, Thunder. I've missed you.
I missed me, too.
