Three days… Allan gave them three more days to stay in the Order. During that time, Noah continued to listen to Rowena's stories during her time as a nurse. The Order was a widespread organization and had multiple subsidiaries—SCC being not one of them, only a partner.
Most prime members of the Order get to travel all over the world, and Rowena also had that kind of privilege as one of the veteran nurses in the field. Same with Luca before. However, instead of business and leisure, Rowena's travels were most likely about charity work and healing small villages.
In return, Rowena picked up a few things from Noah. The witch didn't speak about what he was before becoming a witch, but he did seem to have been doing charity work despite being an assassin. As Arsene did business with those who could pay the assassins, they didn't care about Noah's dealings.
