One thing that I would like to see done with Fiona's character, Nica, is that I'd like to see her come face to face with Tiffany's Bride of Chucky doll form. That would truly be historic.
Also, for Season 4, I think that the creators of the series should go back to the murders of Charles Lee Ray's parents, because I think that there's more to their murders than meets the eye. Also, I think they should also go back to the night when Charles Lee Ray was killed, and explain what really happened between Nica's mother and Charles Lee Ray; because we only got Chucky's side of the story; I don't think we were told the whole story about what happened between them.
Look Chucky will kill me if I say this wrong but season 4 I have to be careful with what I say here because Chucky could literally come kill me but it will be cool to see a season 4 but I don’t see it happening now Chucky if you are seeing this comment I love you you are my favorite horror character but all I am saying is they can’t make season 4 without Chucky how does that work plus isn’t he a Ghost now which makes it a lot harder to produce season 4 without the main character because the main character is technically in it but he ain’t in it if you know what I mean a ghost is not the same then the main character being alive if that makes sense
