Question: When Harry and Hermione are using the time turner, I have two questions about that scene. One: Why can't anyone see them? IS this crucial to their mission? Two: Before they go back in time, we see that they already have (Hermione thinks she saw herself in the tree's.). But this means that there would never be an end to the chain. It's a time paradox.

Chosen answer: They can't be seen to avoid people asking questions. It's generally known where Harry and Hermione were during the course of events, so if somebody later claimed to have spotted them somewhere, people might realise what had really happened, which could cause them problems. As for the paradox, I don't see one - it's a simple course of events. Harry and Hermione live through the chain of events once, including a couple of unknowing interactions with their future selves. They then use the time-turner to travel back and re-experience the events and interactions with themselves again, this time from the alternate perspective. They catch up with the time left departed from and continue onwards. It's pretty straightforward, with no obvious paradox involved.
