When a ridiculous scene inspires you to fill a crucial future plothole.
Also hey, I used another Final Fantasy X plot point and only realized it much, much later.
Phaedra shoots up from her chair, angrily putting a finger in front of Cheth's female half. The death god's full red eyes stare back defiantly.
Phaedra: THEN PROVE IT! Show her to me, then! SHOW ME HER SEAGHOST!
The female half's eyes fade to white again, and she stares, dumbfounded. She looks off to the side, starting to feel worried. She grimaces, saying something very quietly in the God's Tongue.
She bows her head and clasps together in thought, completely taken aback by what has been asked. Phaedra gloats.
Phaedra: That's what I thought. You don't have her, because her soul is with her mother. Shoshana HAS no seaghost.
