In Spitfire's dream on Sol (Martian day) 450, some human kids run up to her and speak with her. Spitfire knows about humans from the videos and pictures she has seen from Earth, sent by NASA. While she struggles with English in reality, in her dream, there is no language barrier, so the kids speak the same language as her. Spitfire has physically languished on Mars, not being able to fly or exercise much. Her depression stems from the fact that once back in Equestria, she isn't as strong as she used to be, and she thinks she's worthless. There are four kids: A young girl, a young boy, an older girl, and a girl older than that - a teenager.
