Awakening Oboe (めざめるオーボエ Mezameru Ōboe) is the fourth episode of the second season of the Hibike! Euphonium anime series. It was broadcasted on October 26, 2016.
With the training camp over, Nozomi comes to thank Kumiko for her efforts and then decides to visit the clubroom and say hello to Mizore. Kumiko tries to prevent them meeting but to no avail, and Mizore runs off. Kumiko and Yuuko search the school for Mizore, who reveals that she still thinks of Nozomi as her only friend (to Yuuko's frustration) and worries that Nozomi quit without telling her because Nozomi doesn't care about her. Nozomi is brought in and the two reconcile; afterwards, Asuka remarks that Mizore is calculating and self-serving, angering Kumiko.
