Martha fairly beams when he takes her hand. While she completely respects what he wants, she's always appreciated physical touch. Perhaps it comes from being friends with Jack. And then marrying Mickey. Mickey. She can't think about him. Not here. There's too much loveliness to enjoy.
But it does bring up a voice in the back of her head. That she needs to be careful. Gentle flirting is one thing; Martha enjoys gentle flirting. But she needs to be careful she doesn't lead him on. Or Gaeta. Or at the very least, she needs to sit down and figure out what the hell she's feeling.
It doesn't seem so important here though. All she knows is that it feels good and she'll continue doing whatever she will so long as it continues to feel good.
