“Did you miss me, Celestia? I missed you.” - Discord, from his first appearance.
 
That line should’ve gone to Trixie. Because so many bronies do miss her! :p

@Background Pony #71A1  
Thank you captain obvious.

Cause and Effect:  
Starlight makes a new friend, which is actually Trixie. Twilight Sparkle is a little surprised to see Trixie came back.

“Why, of course! What other rival of your’s could fill such a role? Considering that the other candidates you’ve either reconciled with, or have left to loiter around in another dimension.”

 
I should make a meme out of that…

@Tragiclady  

 
Heh. Writers and artists have been working that angle since the first episode of season five.

@Background Pony #71A1  
Shh, I’m trying to keep people intentionally confused so nobody knows what my actual opinion is.

On one hand, I want to get hyped since Trixie will be in it. On the other, there is a chance very little might actually happen in the episode so I shouldn’t get my hopes up too much.
 
If I was a fanfiction writer, here are three ways I would have this story end.
 

@Cirrus Light  
Keep your expectations tempered. This show is not very deep and such a thing is probably beyond it’s scope.

@Background Pony #5337  
TvTropes isn’t unbiased. It can be a bit difficult to spot, but they tend to follow specific trends more than others.
 
As for Trixie’s magic, it won’t really matter unless she’s on Twilight’s or Starlight’s Level, honestly. And I don’t think that would be a good idea at all. She’s closer to Rarity, who is skilled in her own right.

@Starswirl  
Oh, sorry, I wanted to reply to @Cirrus Light , but messed up with the buttons.

@Starswirl  
I, for one, only hope they had not followed the fandom in the “her magic is only for show” nonsense (that’s given for true even in the tvtropes page), when, in the few seconds of her two episodes in which she is using her real magic, she puts up a pretty good display of various magic abilities.

@Nightweaver20xx  
What do you mean didn’t not not say it?  
What does that mean anyway?

@Background Pony #5337  
That is true.

Some semi-related thoughts in the comments to
 

 
Something I’m hoping for this episode, which we probably won’t(?) see: Why did Trixie pick up the “The Great and Powerful” title? What kind of pony is underneath that facade? Or is it just truly how Trixie is?
 
I decided to run a little analysis: In “Boast Busters,” Trixie refers to herself as “Trixie” 21 times before the Ursa shows up, and uses first person pronouns only 3 times (one of which was for the phrase, “anything you can do I can do better,” kind of obviously a reference/quote :P ). Once the Ursa shows up, though, she doesn’t use the word “Trixie” or “her (referring to herself)” again until right when she throws up the puff of smoke and runs away, and uses first person pronouns five times in that bit of distress.
 
In “Magic Duel”, though, when she’s got a personal vendetta against Twilight she uses 5 First Person Pronouns (FPPs) in her first line! Her use of FPPs tapers down and she starts referring to herself in the third person again, until the end, where she apologizes to Twilight and again uses FPPs.
 
(MLP Wiki transcripts for the episodes)
 

 
So it’ll be really neat to see how she is now, see if this trend of using FPPs only when emotionally intense holds up (scared of Ursa, deeply angry at Twilight for ruining her life/mad with power, and then when apologetic at the end, deeply remorseful/humiliated), and most of all, if we can’t get some info on where her big apparent ego came from. It’s so massive it seems like it’s some sort of compensation. But, only character development will tell.
 
I love some of the WMG’s about her.
 
Especially the one about her possibly having a much more prominent appearance. She’s a really interesting/neat character, if they can keep up a good characterization of her. Honestly I would’ve been really happy to have her in Starlight’s place! Just imagine that! If she’d gone off and started some faction and played all of Starlight’s roles.
 
Perhaps one reason it’s so interesting is that I’ve sat on the verge of doing something like that, myself: going aloof above everyone to compensate for insecurity and esteem. So afraid of rejection that it’d be better to try to become great so that large numbers of people would die to get to know you, never mind be lucky enough to get close.
 
“You don’t love me?… Fine, The Great and Powerful Trixie doesn’t need some little weakling’s admiration! You don’t deserve the honor of my time! I’m not some nobody, I’m The Great and Powerful!”
 
But it may also just be a character for a stage show.
 
It’s interesting.

@Starswirl  
Well, I remember one of them deliberately deciding to create a friendship problem between three friends that did nothing to her, and then messing with a spell that resulted in depriving all the inhabitants of Ponyville of their will, so to have something to report to Celestia.  
To say one.

@ChuymaruZ  

 
Fact is that Trixie is not evil enough to need reformation or redemption. She is basically a decent pony, with many defects and a pretty bad luck, and that’s why so many people like her.

@Background Pony #5337  
Yeah! Remember that time one of them bought an artefact which she was told to her face was too dangerous to use, just so she could take petty revenge on somepony who did nothing to her directly?

@DoomPony  
Oh! Like none of the Mane 6 has ever messed up with dangerous magic artifacts…

@Background Pony #71A1  
But she didn’t not not say it.

@Nightweaver20xx  
Trixie did not say she would screw Twilight Sparkle.

@Background Pony #35EF  
Maybe Trixie sees one final chance to screw over Twilight by pretending to be Starlight’s friend and then undermining Starlight and Twilight’s friendship. That would be a dark episode, but it would be dramatic.

@Nightweaver20xx  
I know that Twilight Sparkle saw Trixie in Magic Duel, but what does she want with Twilight Sparkle?

@Background Pony #71A1  
She lied. And then Obama cried.
