More than 60,000 Allied soldiers died in the Battle of Dunkirk, which partly explains why Will believes Geoffrey is “lucky” to have survived with intact arms. Yet Geoffrey sustained his wounds not at Dunkirk but in London, during Nazi bombings of civilian targets that killed many of Geoffrey’s loved ones, a detail that emphasizes the dangers of World War II to civilians as well as soldiers. When Zach speaks up for Will’s artistic talent, it emphasizes yet again that Will’s talent has flourished due to the support of his friends and community.
