Mills pulled a staff member into a nearby coat room and knocked the man out as 'gently' as she could. She switched into his clothing, stuffing a few hundred dollars into his socks to hopefully make up for any embarrassment or trouble the man may later face. She pulled her hair down from all the clips and pins and pulled it into a neat braid that she noticed was customary for anyone who walked in and out of the kitchen.
Confident she was at least disguised enough to blend in, Mills made her way into the scullery, and toward the back door. Someone else walked in behind her, gossiping about a woman, who was somehow 'knocked' to the ground, and based on the description, Mills knew it was Mina, and that was her distraction.
