A Twilight episode on my birthday.
 
How appropriate.

Later posts reveal that the friend is Discord. And its the episode he sings in.
 
Get hype.

Twilight shouldn’t go anywhere near Cadance, it always means trouble (Queen Chrysalis, King Sombra, the Equestria Games, Sunset Shimmer…)

I pray to God for that sicj friend to be Spike the Dragon of Equestria.

WHOO BEST PRINCESS! YAY PINK ONE!

What rhymes with Cadance that works just like “damn it”?

@anonymouspegasus  
And now I’m picturing Shining Armor and Cadance as Brad and Janet from the Rocky Horror Picture Show.

@PonyPon
 
This is the mentality that puts lunatics in unscripted peepshows on so many channels.

@Kazapsky  
Yeah, but we don’t expect most real life humans to be worth watching.

@Kazapsky  
Actually, when they do need a small novel, they slam them for that too.

@NostalgiaSchmaltz
 
Oddly enough, most real-life human beings have a personality that can be described in one or two sentences.
 
And yet when a fictional character doesn’t need a small novel to describe how they act, people slam them for it.

Yeah, it looks like it’s confirmed that “Three’s a Crowd” and the Weird Al episodes are separate and it’s just been a mixup:

@NostalgiaSchmaltz  
I expected more out of them when they appeared in season 3. I have to agree with you that they’re still bland, but I just can’t bring myself to hate/dislike either of them.

@anonymouspegasus  
inb4 people complaining about it being a wasted episode because Cadance has no characterization.

@anonymouspegasus  
And that’s kinda the reason I don’t like her or SA, they’re just bland.
 
Cadence is a “happy pretty princess”, and Shining Armor is a “big strong brother”. They don’t really have anything else to their characters, and it’s rather annoying that they’ve been in like 4 or 5 episodes now and they’re still as bland as when they first appeared.

@NostalgiaSchmaltz  
Yeah. Pity she hasn’t had much development; I kind of like her and Shining Armor. A couple of reasonable ponies in a world full of half-lunatics. :P

@Background Pony #8298  
…GTA IV did not invent the term “three’s a crowd”.

“Three’s a crowd”?
 
GTA IV.

@anonymouspegasus  
And hopefully they can finally give Cadence some meaningful characterization. :\

@Prof.NightJack  
So long as we get the Weird Al episode, I’m happy either way, especially since this one could go a little more into how close Twilight and Cadence really were back then.

@Prof.NightJack  
Yeah, that does seem likely.
 
Wonder which intern fucked it up, then.

@NostalgiaSchmaltz  
Most likely a mix up of the title and synopsis.

@Itsthinking  
So that may mean that “Three’s a Crowd” isn’t the name of it.  
He’s known for joking around but not lying, so it’s likely he is in one just not this one.

@Itsthinking  
Ah, so it’s just moved later in the season then. Hm. Wonder why they did that.

No Weird Al appearance on MLP? Oh well.
