"Watch your mouth young-" Rebecca started, before the bright FLASH erupted, covering them both as they transformed, along with reality. Unfortunately, however they would change, Rick would still be unaware of who he was, thinking whoever or whatever he was going to be, was always how things were.
Neither could know that in their struggle, Rebecca had altered the camera's mode, changing it to blend in setting 2. This was about to transform the subjects, this being the former Rick and Emily, to better match with other people in said photo. When the camera flashed, the people walking behind them was a family of 3, and now that family was about to get 2 new members.... of course, to them, they've always been just part of the family.
The question is, what does this family of 3 look like? And just how are Rebecca and Emily about to fit in?
