Year: Irrelevant, Location: A Bubble Outside Time
"if you do not wish to be called friend that is fine," I murmured in Amese sitting down in my favorite chair which was located slightly to the right of the couch if still facing it. "However I must point out that I did not trick you, nothing I said was strictly a lie. Henry did not betray you, betrayal implies a certain amount of premeditation and I assure you he had no idea what the consequences of his actions would be. You can not have met all of the men in your timeline or even on your planet so they cannot all have ostracized you. As for calling Xanthia a throwback, She is a very lovely and helpful young woman and I might point out that without her generation yours would never have existed."
Switching to English I continued. "I do, however, thank you for the complement on my home. Personally I have always felt that the sourceless light your generation seems to favor resembles something out of a cheep mid-twentieth century scifi flick. Now, you have said you want proof of our claims. I can of course take you to a different time line, that would suffice I suppose, but if I do that I might as well just continue the mission which would effectively be kidnapping you. I prefer not to take that rout.
"Our mission, however, is to save Henry Marsdale or rather to save him from himself. With what he knows, on his current chosen course, he could do great irreparable damage. I might point out that Henry did get your timeline on his own, and while there he did consider you a friend. if Xanthia and yourself will consent, and the others as well, we stand a great chance of being able to appeal to his better nature and come to a peaceful resolution. Your topography and geology skills will be of great help, and I'm sure that you will agree that whatever happens here will be far more interesting than sitting in a classroom.
"Now," I leaned back in my chair this long speech having winded me slightly, "what questions can I answer that may help you make up your mind?"
