Mr Grove (spoilers)
I know he was an ass and took Ms Mardle for granted but I was so happy when they finally came back together. It was so heartbreaking in that final scene when Meryl came outside to find him passed. Josie loved him so much and I believe he loved her just as much. I'm glad they came together in the end and the children will be in perfect hands with her. They love her and she loves them. He will always be with her. If her story were to go on, I bet she would not find another love and be content with what he gave and left her. So bittersweet.
I cried.
