I'm a bit curious about the reincarnation cycle. The fire nation tried to kill all the airbenders, but I assume they did so while Avatar Roku was still alive, otherwise, the airbender Avatar would simply reincarnate into the next water bender. So was Roku still alive at the time? And if yes, then why didn't he stop the fire nation?
