Sameer and The Chief quickly volunteer as their time with Diana have inspired them to fight for a cause. Charlie, however, hesitates. You see Charlie can’t shoot anymore. His PTSD is too overwhelming and he’s afraid he’s become useless. “Maybe you’ll be better without me,” he says, pained by the idea that he’s too “broken” to help.“But who will sing to us, Charlie?” Diana asks. It’s a simple question that brings a smile to Charlie’s face, a song in his heart, and the group continues on their way.
On the surface, it’s a tender moment. One that shows just how close this group has become since dropping onto the front lines of World War One. But with one simple line, Wonder Woman has redefined what it is to be a man.
Patty Jenkins’s Diana, doesn’t ask Charlie to continue to fight for her. She doesn’t need him to kill for her. She doesn’t try to encourage him or make him feel guilty for not being able to kill anymore, or turn him away because he’s can’t. She simply asks him to do what he can. She simply asks him to sing, and tells us that we don’t need to fight to be strong enough to stand beside Wonder Woman. - “But who will sing to us, Charlie?” The Defining Power of Wonder Woman
