Thoughts about this movie *Spoilers* / Most beautiful short scene ever

I just watched this movie, and it was so moving (even for a guy), that I decided to think a bit about it and read the thoughts of the others here.

*here comes the complicated part. I hope you understand what I mean, but I am not sure if I can be clearer even on my own (quite different) language*

I see that the main question here is "If Sam did come back or not". Well I am pretty sure she did. The handwriting everybody mentions is referring to what the professor in the first part of the movie about the case in those villages. He said something like "Then in some time she recovered, but still retained the other girl's habits" (or something like this). Sam did return, but she kept some parts of her mother. This is beautiful, isn't it? They finally got closer to each other.

But there was this moment that really stroke me and I had to watch it a few more times. It is when they were in the store and they were having this fight about her counselor being in DD's office. Then they stopped and she asks him about "why he is not able to have sex with his own wife, while realizing she is in front of him", and he answers because she is 6 feet under the ground After this moment she makes a slight try to kiss him. It is barely noticeable and I found it really, REALLY beautiful. I can say, that for me this is the shortest most beautiful scene I've seen in ages (if not ever).

This young actress has a big talent. I can't wait seeing more of her acting.
