One hundred and twenty years after his death, Charles Darwin relaxes peacefully in a beach house in Malibu, California overlooking the ocean with a young girl named Sarah. Their relationship, never fully explained, is unique: she makes him banana smoothies while he reads a trashy novel, and smokes a joint with him in the second act. Played by Anne Powell, Sarah is the weakest character in the play: the script gives her the ability to play a strange, nuanced girl, yet her lines are often delivered without power and expressiveness. Nonetheless, it is interesting watching her character unfold, and witnessing her relationship with Darwin—particularly her casual slang (often infused with cursing) juxtaposed with Darwin’s elevated diction. The two make an unlikely, yet weirdly appropriate, match.
