re: OP

What is it precisely that you feel the Retcon "glosses over" or "cheapens"? Use more exact terms, please.

It's not "favoritism" to bring back Vriska and not Feferi. Vriska is a real character (in fact, she's the main character), and Feferi isn't. Vriska has always been important to the plot, and making an accusation of "favoritism" is a little ridiculous because at the end of the day, it's Hussie's comic and they got to decide, ultimately, how the story played out.
