Seeing no reason to rush off, River sat down in the offered chair and figured that they had to talk. Sharing wasn't something that she was good at, but if there was strategy to be worked out, it would obviously be best to do it between the pair of them. That kind of sharing she could do easily. She wished that she could trust people, but it didn't seem like she was programmed that way. And yes, River only thought of herself as programmed. She didn't quite know what the real her thought or felt at all. If there was an even real her to begin with.
"I couldn't quite tell actually, but it was definitely something that he was injecting into himself. I suppose it's medicine. I can't imagine Tempus doing any sort of recreational drug." The thought though was enough to seriously amuse her and a smile crossed over her lips. Though she could buy ill. Of course what kind of ill was vast. He kept running around, god knew what sort of things he got up to. She wished they had the answers, but it didn't look either one of them did.
River shook her head and grinned. "No, it doesn't. Well not unless you make him very very mad. It does kind of make me wonder though. How far you'd have to push him before he crossed that line." Maybe that would be her next project. Perhaps the best way to destroy the Doctor was to get him to destroy himself. From the inside out. That did sound kind of fun.
"As am I. I know that we're only using this as a means of transportation, but we should still be on our guard."
