Tear Jerker / Peter Pan in Scarlet

• The reveal that Michael died during World War I. It only has a few passing mentions, but each of them really saddens the mood. Made even worse because Peter being, well, Peter Pan, he doesn't remember Michael. Thus, he doesn't understand why everyone becomes sad and refuses to play when he suggests they play war.
  Slightly: Michael went away during the Big War. He was... Lost.
• Hook reveals that he doesn't have his crew anymore because he sent them do their bit in the War. They never returned. While he likes to think they just went on to live their lives, it's pretty clear that he knows they simply died during the War.
  “I sent them off to do their bit in the War,” said Hook. “As every man should. They sent me postcards first off. From Belgium and France. Then they forgot, I suppose. The postcards stopped. I imagine they were having too good a time. I imagine they were too busy living it up on booty and the spoils of war. Spending their loot on cake and beautiful French women. Unwilling to return to the drudgery of life aboard the Jolly Roger.”
  Wendy nodded. “I like to imagine that as well,” she said, “every time I think about my brother Michael.” Their eyes met for the briefest of moments, during which they understood each other perfectly.
