Soulmate AU

Dottore was down in his lab, writting away on his desk. But then, one of his segments told him that there was someone who stumbled upon the lab, the segment was bothered by the sudden appearance.

"Prime. Someone's by the entrance with me. Seems like this one is intriguing enough to become a test subject." The segment said to Dottore, via linked minds. Dottore then made his way up towards the entrance of his lab to meet them.

"Who are you?" He asked in a deep, husky voice.
