Do you think Hussie desides the fate of a character just to mess with the fans? (ex. fusing Nepeta with Davesprite) Or do you think there is a deeper meaning to each character's path?

He did that for some of them. Such as Fefeta never speaking was because the fans desperately wanted Nepeta and/or Feferi to be relevant again.

But I feel like Davepeta was a good thing for Davesprite’s character so I’m not sure if I’d categorize it here
