The addition of Grayson, Doe, Emery, and Tori to the group evokes an important connection to another part of American history—the underground railroad. As with the original underground railroad, Lauren’s group operates as an ever-evolving informal network of support in the face of extreme danger. There is also a significant resemblance between Lauren and the most prominent hero of the underground railroad, Harriet Tubman. Both are extremely strong-willed, fierce, and courageous black American women who put themselves at great risk in order to bring about a brighter and more just future.
