Okay, multiple things here.
One: Naomi is now considered a main character
Two: Between Terror C and Retrieval is new chapter centred around Naomi called "Escape". This brings the total number of chapters to 4.
Three: They should be uploaded over the course of the next two days and will be accompanied by the next two chapters of the Covenant Invasion Series, the next chapter of the NCIS series and the second chapter of the Camp Terror Series.
