You are female Stiles.
Underneath the crime and the supernatural, you run Beacon Hills. Any threat to the town or your pack, it's handled swiftly and without mercy. You play the part of a bumbling human while hiding the truth. When the Alpha Pack came into town along with the Darach, you handled it as effective as possible. But you were seen by the one person you didn't want to see.
Derek Hale had seen this part of you. The ruthlessness and merciless killer. As soon as you knew the Alpha Pack was taken and Derek was distracted, you retreated.
It took a few days, but while at your command center. Derek enters and watches you with his usual piercing stare, remaining silent and watching as you organize commands for your subordinate electronically.
