The entire reunion between the sisters is this. As Nisa says "This touching reunion would bring even the most hardened heart to tears."
Neptune: "Nepgear? Gosh, did I miss your face..."
Nepgear: "You're... really my sister, right? I really managed to help you, right?"
Nepgear: "Sis... Waaaah! Neptune!"
Neptune: "I'm sorry I left you alone for so long. But you know what? I'll always be with you from now on."
