"Bill hasn't been traveling with me, nor does she know me as well as River. She was pretty much inexperienced, which has both it's pros and cons. You gotta admit, that it's not easy to not automatically expect the worst, with your track record, especially when they don't know you as well I as I do." The Doctor hung his head. "River's been around. She also doesn't have the personal experiences that Jack's had, so she's able to see things from a different perspective." He weighed Missy's journal in his hands, again reminded of River's journal, which he always carried in his coat pocket, near to his hearts. "Did she tell you that she was raised to assassinate me?"
The Doctor looked up from the journal, meeting the Master's eyes, not saying anything for several moments, then simply lifted his hand for the Master to take. "I know," he muttered.
