Euterpe's little muse heart is breaking
Euterpe just blinked at him in shock. "But..." she didn't know what to say. She looked down at her wineglass and tried to formulate and organize her thoughts. "But... she loves you," Euterpe said, when she eventually dared to meet his eye again. "We love you. And Thalia... she's so happy. Happier than she's been for such a long time, maybe since the days of Greece. You're our father. Why can you not be happy that she's finally found peace, even if it's with a Titan? She meant no disrespect, father."
