Jon had become a part of Sarah! Well, at first Jon was a part of Sarah, but then his presence started to get "mixed in" with Sarah's presence, all the way to the point when Sarah and Jon (as separate minds) no longer existed.
Now there was one mind, made up from the merging of Sarah and Jon. Since this new mind was in a female body, it considered itself a girl. And therefore, kept the name Sarah as her own.
She looked down at the stone (which had created her) and wondered what to wish for next.
