To watch Henry suffer such deep emotions and for him to allow all of us to see what PTSD has done to just one person truly breaks my heart. His deep love for Khan and Keanu is beautiful and proves animals help heal instead of always a person. To see him at the beginning of the film and then at the end makes me love it even more!!!! I really hope he continues to seek the happiness he so deserves without ever giving up. It is a beautiful love story.
