this ..i find it so sad when she realizes he’s not as far in their relationship as she thought. Tho I don’t get why ppl assume it is the very last kiss. She says ‘and a last’ not because it is the last (no way in the world do i believe that between this for her and AtM that they didn’t kiss..puhlease) for me this moment was a continuing issue of her personal demon, a reminder that one day she’ll pop into his life and he won’t know who she is. That is the demon that follows her in every single adventure we see. She experiences a moment of it in every ep she is in. This is just continuing that.. going with what she told Rory in the Impossible astronaut.
