Sophie's calloused hands from all those years of working as a maid is the reason why Benedict was able to recognize that they had met before when they touched hands - the young ladies of the ton usually have soft hands, so a mysterious noble lady with rough hands would've been noteworthy.
also the fact that he was able to recognize her hands even though he had his torso sliced open and was inebriated.
Benedict Bridgerton, everybody. 👏🏽
