Howling:River giving the Doctor her regenerations

Did River use all of her regenerations to revive the doctor, or did she use only one to revive him and gave him all the rest? If so, does the Doctor have regenerations after his normal thirteen regeneratioos? (it does sound like a way to keep the show going after the Thirteenth Doctor dies). 98.242.167.50talk to me 12:46, October 3, 2012 (UTC)
