There’s a part of her that feels very comfortable and very attracted to this new doctor because he is the same guy, but clearly he’s not and clearly she’s saying goodbye to this other man that she’s been in love with. For the doctor himself there’s just another heartbreak and another tragedy and he’s back on bad wolf bay were he last experienced this, he’s saying goodbye again and bidding farewell again and this time it’s closing forever and there’s no going back. And in gifting her this other doctor he’s not really allowing himself to go back either. - David Tennant
