User blog comment:CF12/Why Katie and Sadie Should Not Return/@comment-2147650-20150707155845

I completely understand both sides of the arguement. On one hand, you want them to come back for the development that they could easily get because of their lack of screentime (plus the nostalgia factor that a lot of the fans enjoy). On the other hand, they could easily be a waste of a return if not pulled off correctly.

Personally, I'd like to see them back. They didn't really annoy me all that much and despite the fact that they rank low on my rankings I think they could be great in another season/series.
