Points if you get what episode of a 'certain show' this is referencing as well.

Wright begins to explain to Spike.
"Well y'see, this is how it goes...
there's a bit of a 'problem' that went down in this town a couple days ago...
a 'murder' happened...
only two people could have committed it, and we have no idea of knowing which one."

Spike stares "M-M-M-MURDER?!"

Wright nods.
"Yes, an unfortunate tragedy,
a young dragon was struck down, and we had all thought he died.
We have been told you're from another... 'dimension'
does this mean you have some way of time travel?"

Spike sighs "No... i'm sorry."

Wright gets up "It's fine, i'll defend you anyway,
but those in charge may not be so willing without your help..."

Spike gulps "I-i'm sorry... I really can't time travel."

Wright then walks away.

Suddenly, none other than Silver Shill appears in the room with Spike, wearing a gray uniform with a toolbelt.
(Yes, randomness everywhere.)

Silver smiles fakely "H-hi..."

Spike stares "W-who are you?"

Silver starts to shake "W-where am I?"

Spike replies "Uumm... prison.
or jail... I get the two mixed up.
How did you get in here?"

Silver Shill screams "Huh?"

Spike replies "Don't you 'huh' me, how did you get in here?
You used magic... which means you're from my world!"

Silver screams again "AAAHHH, MY POSITON HAS BEEN COMPROMISED,
ASSUMING STEALTH MODE."

His suit turns to resemble many different area's of this world.
"Initiating color match, color match come on, dadgum it!"

Spike tilts his head.
"That was amazing,
are you from the future or something?"

Silver screams "AAAHH! WHO TOLD YOU THAT?!
MEMORY WIPE!"

He throws a baby wipe Spike pulls it off "This is a baby wipe..."

Silver groans "Aagh, alright, you cornered me,
i'm... a time traveler."

Spike replies "So wait, if you're from the future, do you have a time machine or something?"

Silver shrugs "That's...kinda how it works."

Spike smiles "Can I borrow it?"

Silver screams again "OUT OF THE QUESTION!
You know this is sensitive extremely complicated time equipment!"

Spike ponders "It looks like a time machine."

Silver screams once again "YOU SHUT YOUR TIME MOUTH!"

Spike laughs "I think you're just crazy..."

Blendin screams "NO! I'M SERIOUS!"

Spike replies "So who are you again?"

Silver continues "Silver Shill,
time anomoly removal crew year 207012,
i'm supposed to stop a series of time anomolies,
but my time machine malfunctioned, and took me to this alternat dimension.
I can't find my way home... and I have to... because I have to stop.. him."

Spike ponders "I think we're from the same dimension...
you're trying to stop Enigma right?"

Silver gasps "Y-yes..
h-how did you?"

Spike replies "I'm trying to stop the same thing as you,
and I have an idea on 'how' to do it.
It's fate you're here...

Let me explain...
If I help these dragons travel back in time to see this murder happen, and determine the killer.
then they'll give permission to these ponies to dig up this source of magical energy, which would give them the magic they need.
so that they'll let my friends free, including Velia the Draconequus.

If we have her, and another Draconequus Discord, WE CAN STOP ENIGMA.
But I can't get her back...
without doing all of that.
So I need your help, in order to help them, so they'll help them, so they'll they'll help them.
so that she can help us."

Silver sighs "But...
how do we get home from there?"

Spike sighs "I'm...
not...
sure..."

Silver sighs again "Sooo...
what would be the point?"

Spike groans "Well...
we need Velia TRAINED, before hand.
apparently she has no idea how to use her magic...
But my friend Twilight can train her.

And we need her BEFORE we go home.
we can figure that out from there.
and hold up...
you're that guy that worked for the Flim Flam Brother's right?"

Silver screams "EEP!
Yes...
I was just...
I was trying to make money, and it was making people happy...
and..."

Spike tilts his head.
"Why did you need money?
YOU'RE A TIME TRAVELER.
Does this money even work in your time?"

Silver sighs "Well...
no...
But I was trying to buy something...here...
something really expensive..
i-it's not important."

Spike shrugs "Alright,
now..
do we have a deal?"

Silver nods.
"We...we do...
Go ask around what time period it was, and we'll set off.
TOGETHER."

END OF CHAPTER So yes, Silver Shill is basically Blendin Blandin.
yup.
