Need to write an addendum to John about this stuff. John who is probably Jane's grandpa from the past, or maybe not really the past? Maybe like a young grandpa clone who lives in that ghost world where you saw all those other kids, including those two Dirk and Roxy-looking kids, and what you think may have been literally a sleeping Roxy, but you aren't totally sure? Why does everything have to be so COMPLICATED? Whatever, no big. Going on adventures isn't about UNDERSTANDING them. It's about being brave, and leaping into fistfights without thinking ahead.
You finish off your note with a few more friendly words, and something vague about who you really are. You are just following your alien friend's advice on maintaining a bit of secrecy so as not to cause timeline problems, but boy is it hard keeping secrets. You can't help yourself, and slip in a subtle clue that your grandmother is actually his pal Jade. Tee hee. You figure if John is even half as sharp as you, he will pick up on that right away. It's ok, it'll just be a little secret between you and him. The pretend-British alien doesn't even need to know.
