You can't hurry genius. Never set specific dates because you cannot foresee the future and guarantee delivery. and if you yourself create an expectation it is not so unreasonable for people to get pissed when you don't meet it.
So please take whatever time you need to make Chapter 4 the absolute best you can make it. That's essential and all that I, personally, ask of you. I hope I'm not alone in requesting this.
Chapter 4 is your finale too, so I sincerely hope we are going to go out with a bang (so to speak!). There must surely be avenues for a spinoff with Evie's sister clearly (from what has been said over the phone) conniving with her sister in this situation.
