It is clear that he has other things on his mind and a lot of things that he has to think of. So, when you put your hand on his leg he immediately put his hand on your hand. He looks at you as if he wants you to answer him and tell him what to do. But you can not. This is something that he has to answer to and not you. Then you watch him as he takes a deep breath and looks you straight in the eyes.

NICK POV
He can not seem to get over himself for he knows that when he walks through that door, he will only be met by sorrow. His world is not always been bright and shiny but since he met you he wants to stay in the bright and shiny part of life. He has been enjoying being happy probably for the first time in his life and now when he walks through that door he brings whatever sadness there is on himself.
