The moment in the seance between Emma and Killian was to focus on the touching.
The moment Killian reaches out for Emma’s back is once again to focus on the touch.
Even at Granny’s the two of them bonding is about touching. Not on a physical level but on an emotional level.
Every scene was about touching and the inability for them to do so because of the curse. This is a set up for a big CS touch moment aka a True Love’s Kiss.
