3 Works in Cagnazzo/Scarmiglione (Final Fantasy IV)
Kain didn't know who to feel worse for between Scarmiglione and Cagnazzo.
Before they go to fight, the earth fiend smiles weakly as he says, "It'sss been sssuch a good life with you...my love...always...and forever." to which Cagnazzo frowns, telling him, "You sound like you're saying farewell," and he squeezes his hand and kisses him sadly upon realizing it was exactly that.
Even angels can fall, and Eidolons are no angels. They make their choices and abide by them, however unwillingly.
