What gets me in this scene is George lost the most important person in his life and he’s grieving, he’s terrified, he’s confused and he doesn’t know what to do. But he sees his little brother come in. And he knows that he could have lost him too and that in itself is not something he could deal with. So he is able to tear himself away from his other half to hug his baby brother. The brother he teased mercilessly and pranked. The brother he was never really the nicest too. But it didn’t matter in that moment because he was alive and he could not take another person he loved leaving him.
