Seriously, we were hoping to see Trixie in S2, and he returned in S3. We think the same of Gilda, and well, since she was a weak and flat character she obviously didn´t return. Then Flim and Flam return and...ufff...
But, why those one-shot characters can´t return? I refer to:
Lightning Dust
Cheese Sandwich
Maud Pie
Suri
Diamond Dogs
Steven Magnet
The reason of why the two characters mentiond above returned and the other don´t was because they were fresh and really good characters, a large amount of fans, and because they serve to do a contrast to the protagonist, showing what they could have become.
AND WHY THESE CHARACTERS CAN´T RETURN WHEN THEY HAVE A LOT TO SHOW!!
LD served to show the bad aspects of Rainbow Dash, and since a lot of Wonderbolts episodes are coming, i can see her returning.
Cheese Sandwich good development and is not really fair that they only use him for the keys.
Suri was another counterpart to Rarity.
These two last characters (Magnet and DD) got a lot of fans and fanfics, and the first one was a FUCKING MEME GODDAMNIT!!
So, ¿What are the reasons to not bring they back?
I WANT ANSWERS!!! I WANT TO KNOW THE TRUTH!!! YOU CAN´T HANDLE THE TRUTH!!! FORGET IT, IT´S CHINATOWN!!
PD: I want Chrysalis and Zecora to return also, duh.
