Forum:River Song's sacrificing her regenerations

Did River Song sacrifice all her regenerations to restore the Doctor in Let's Kill Hitler? Or did she use one regeneration to save him and effectively give him ten more regenerations and extend his life? 98.242.167.50talk to me 08:50, July 8, 2012 (UTC)
 * She used them all up. The episode was repeated on BBC3 last night (so it's fresh in my mind), and they specifically said so. By the way, signatures go after comments, not before. Digifiend 01:48, July 11, 2012 (UTC)
