A few months have passed since Starlight Glimmer found out she was the biological sister of Twilight Sparkle; causing her to bound with the Alicorn and her friends like never before. After loosing to the new sisters in the sisterhooves social, the CMC alongside Diamond Tiara and Silver Spoon are now forced to chart out their own family trees. One of them is about to discover that a pony they've looked up to and been mentored by is more to them then they had ever known and reveal a well kept secret.

A/N: This is a sequel to Suddenly Sisters - Fimfiction
It is very much recommended you read that story first so you have an understanding behind this story. This also takes place directly after that story's epilogue so during season 7 but not too long after the events of this story's prequel. A day or two later at most.

A/N 2: Just like with it's prequel "Suddenly Sisters 2: Biological Connection" while rated E deals with the concept of adoption. If you don't like this concept, don't read. And while comments and ratings are enabled, if you all can't behave yourselves and avoid leaving hate comments, I won't hesitate to disable comments and ratings. You all behaved yourselves with "Suddenly Sisters" and I expect those who don't agree with Scootaloo being Rainbow Dash's biological sister to avoid leaving hate comments.

A/N 3: The idea of Scootaloo being Rainbow Dash's Biological sister comes from the story "Dear Scootaloo" which is part of the "Dear CMC" series made by Jade Ring. You can check out Scootaloo's part here: Dear Scootaloo - Fimfiction
You do not however need to read "Dear Scootaloo" or any part of the "Dear CMC" series to be able to enjoy this story; in fact this is an entirely different cannon from the "Dear CMC" series. The only story you need to read to understand this one is "Suddenly Sisters".

A/N 4: Also, unlike "Suddenly Sisters", the entirety of "Suddenly Sisters 2: Biological Connection" is told in first person from Scootaloo's P.O.V. so if you don't like that, don't read this.
