>Applejack

The idea was she would turn her whole family with at the family reunion as she reaches 2.0 due to flutterbat. But was now kinda thinking Flutterbat changes her mentally into 2.0 but the rest of the magic lays dormant in her body until she has set her plan in motions. As soon as the whole apple family starts changing the dormant magic in her starts to reward her and changes her physically as well completing her 2.0 stage.

But this spin on it just came to mind today, so absolutely open on different takes on it.
