I love the part in utopia were jack rides on the outside of the tardis And Martha finds him and does CPR and she's like IM SORRY BUT.....HES DEAD then he GASPS FOR AIR and hes like WAS SOMEONE KISSING ME!!!!
Oh gosh, but this isn't funny! Yes, he knows Jack will live again, but he also knows it HURT! And just because Jack is immortal that doesn't mean he can't feel PAIN and the Doctor is just sorry for him.
