Howling:Why did time start again after Doctor Who's staged Death?

In The Wedding of River Song time has stopped moving because River discharges the space suit's energy instead of shooting the Doctor, and we are told that this is an attempt to rewrite a fixed point in time. But at the end of the episode, River discharges the space suit's energy into the Teselecta. The Doctor is not harmed. What is the fixed point in time that has been restored so that time acts properly again?--ANone talk to me 07:08, October 25, 2011 (UTC)
