Bumped into this theory while wandering around the Internet:
12 came out of the regeneration extra telepathic. He gave Rupert a whole dream just by touching his forehead and it took him just seconds to see that the captured Teller creature was feeling fine when he put his hand on its forehead.
That’s why he looked so puzzled after Marian kissed him as a thank you after he had saved the prisoners. He just gained the knowledge to figure out who she really was.
That’s also why 12 panics at hugs! And why he looked so uncomfortable after Saibra had hugged him. He probably wasn’t able to avoid direct contact (as she was so happy to say how she hadn’t turned into him) and had just been inside her head without her permission.
