Wait... Future Lucy and the normal Lucy meeting... It has an affection to the future, but the Future Lucy came back because of the future's uhm... bad things, I think. So... if they do something different in present, it will change the future. And if the future changes, Future Lucy doesn't go back to the present to ask for help...

That time paradox thingy confuses me. (._.)
