Its clear to see from 'Rose' that Nine had only recently regenerated or hadn't managed to look in a mirror yet as he was surprised by his appearance. So I've always thought it was eight who ended it going by that. However now we know that Eight choose to regenerate in to a 'warrior' so he could end the war.
