The smile of hope vs the smile that can’t quite mask the pain behind her eyes. The way she told Mary that she was hurt because of what happened with Tomás, and how she tried to be as sensible as possible while doing it showed very early on that Greer is an incredibly strong character. Even as her hopes are crushed, she keeps her wits about her. Even as tears build up in her eyes and she only feels like sobbing alone in her room, she calmly explains to Mary why she’s reacting the way she is and why it’s a reasonable response. She remains strong even when she feels weak.
