I hope you all realize how important this scene was.
For a father to tell his son it’s okay not to be strong. To cry and feel.
Shikaku knows Asuma’s death is tearing his son apart and he’s trying so hard to keep himself together, and he’s proud of him for trying to be the “man” he thinks he needs to be, but still giving him permission to give in, to cry and mourn.
Because Shikamaru is still a child, his child; his to help through this, and it’s his job as his father to be strong for him.
