Question: I've tried to look for this in the books but I still don't get it. When future Harry and Hermione come back to the hospital wing after they went back in time and saved Sirius, then their selves should have just left again to do the same thing. What happens to them, since it was already done? Where do they go?

Answer: Time travel is very complex. They are going back to fix things, but from out point of view, they already have! But, if you consider when our Harry and Hermionie leave, the previous Harry and Hermionie would enter the room, it might start to make sense. Basically, an infinite number of Harry and Hermionie travel back to change the past, but we only follow one.
