To give context, I'm writing a Doctor Who short story in which there are two versions of the Time Travelling alien, The Doctor. Their personalities and appearence are very different, however they are both known only as The Doctor. So, it has moments like this: The Doctor walked over to the wall, The other Doctor followed. "Wow, look at this." said the Doctor. "I know, it's horrible." The Doctor agreed. A bit less than that, maybe but it's still confusing to the reader. Anyone dealt with something like this?
