This actually goes back somewhat far. I was following up on Sage's original run on X-Treme and there was a point where Emma was put up as stakes in a card game between Elias and Shaw and the only reason Shaw won at all was because Tessa was so good at keeping her thoughts hidden and she helped Shaw win the card game. There have been a lot of times over the years where Emma has been somewhat afraid of Shaw, and I know he almost killed her in X-Men black and only the fact that he had been drugged earlier by Emma's agent allowed Emma to win against Shaw who has always been very resistant to telepathy. One of my biggest hates in shipping is people who ship Emma and Shaw, I hate that, he is an awful human being and she has never trusted him. She worked with him because he ran the inner circle and that was the only reason she ever worked with him.
