Lain wais a series I greatly enjoy. You really need to see all of it, more than once if you can, to get the full story. There are many elements that lead to the conclusion, if you want to call it that. This seems to use an updated version of an old SciFi theme, it leaves you with a mysterie to use your imagination on. I think the scene with the little alien is there to add one more little mysterie to ponder. I was left at the end wondering if Lain was ever a "real" being, or was her life, her whole world, only a program, only imaginary, as in the SciFi story where the whole world was only a creation of one man's dream.
Just a side note on these off topic often offensive posts. A long time ago it was written that we should treat others as we would wish to be treated by them. If we would all remember this, wouldn't it be a much better world to live in, and a much better forum to post in.
