She's touched MULTIPLE people and not read their minds. Like the guy who poisoned her for just one of many examples. He covered her mouth, grasped her wrist, she even HELD HIM UP and helped him walk to find shelter.
Why would she need to read his mind? I mean yes he poisoned her but she probably wasn't thinking about using her powers on him and was more worried on getting him help and getting the antidote. Plus the only person who's mind I'd actually like her to read is her husbands and she can't use it on him .-. it also just feels like the mind reading thing is just to add some twist into the story for no reason (for right now anyway that could change) It even seems like she has forgotten about the power herself
She can only read peoples minds if she is touching them how can you expect her to use her powers? Her powers are basically useless to the story at this point in the story xD the only person she really touches is her husband and she can't read his mind
