Yes, I can imagine. In a much more dramatic way, that's still a factor between the Master and me. Even now - I've been told he's here as well. And time travel confuses everything as well - I might see someone I offended 500 years ago, and it's just been a day or two for them. Or someone I'm going to offend in the future. Like Queen Elizabeth the First! She tried to execute me the first time I met her! Didn't find out what that was about till a couple years later.
