The Red Hook Pirate Crew's response to Toz's message came during one of Toz and Wulf's sparring sessions. Both of them stopped swinging their weapons at the same time as a raven swooped down and dropped off a piece of paper.
Toz caught the paper and read through it, revealing a devious smile afterward. The smile was all Wulf needed in order to understand that the Red Hook Pirate Crew had accepted Toz's invitation to a talk.
The others also sensed the raven's arrival and appeared in the yard where Toz and Wulf were.
The Red Hook Pirate Crew's response was short and only contained three things. Their leader and a few of her subordinates were waiting in Retsy's middle base since it was a neutral meeting location. A demand for Toz to bring the object he offered, or at least proof of it. And to ensure no one noticed that they were meeting with each other.
