Well the story is changing and cesare is not pretending in this life anymore and his not using ariadne too. If this goes on their love story became interesting. Well its still depend on ariadne. Remember what isabella said when she kill the ariadne cesare might change his mind. Means she knows that only her face attract cesare and cesare truly love ariadne but he was only blind by what his mother want for him and lack of love of family.
Just saying though😅
