I’m not sure of the specific context of this, most likely a moment in which Harmony confides in her older sister.
Dissonance and Harmony may be polar opposites in terms of personalities—Dissonance being mellow and collected while Harmony is intensely outgoing and extra—but their bond is definitely one that both rivals and surprises many. This is much to Celestia’s relief, as she may have had some subconscious fear of her daughters repeating the history between she and Luna.
