Mina was appalled by Willow's insinuation. She was behaving differently because she genuinely felt better. Things she had carried with her for years had been lifted off her, guilt she held because she thought she had done something wrong had melted away, and the small hint of hatred that marred her relationship with her sister had been wiped clean.
Hearing her friend accuse her without actually accusing her hurt, especially because she knew everything. Willow, Ash and Cylus were the only people who knew what happened between herself and President Lee, and although the man claimed that her assumption of what occurred between them was wrong, Mina did not care.
"Why would you ask me that?"
"Mina, every time I call you, no, every time anyone calls you, you are with President Lee."
"Of course I am, I live under his roof, and I work out of his home office."
