I should mention that the episode also contained a flashback to the Pearson children with Randall wanting to learn how to box so that he could be tough like Jack. It's one of those instances where the show doesn't have a great way to tie the flashback into the present day, so it feels a little forced. I would have actually preferred to skip the flashback this week, but I will say that Mandy Moore is such a low-key heavy hitter on this show. The look on her face when Jack opens up to her about boxing with his brother? It's like she has just been given the greatest gift and it conveys so much without saying a word.
