Well, toi turn how many hours you'd like to back, like 3. You'd appear in that heure where toi turned the Time Turner, and toi don't want anyone to see toi incase they just saw you, ou areabout to. toi don't want to see yourself, because the first toi in that heure might not know about the Time Turner, and think you've gone crazy, and try to kill the toi that went back in time. Also, if toi get hurt in that hour, you'll feel it in the other you.
"Curious thing, time."
Hope that helped!
