After asking why she is at Crippled Kate's and about Margarita Laux-Antille, Yennefer will tell you that there is a man who escaped from Deireadh prison named Abbé Faria who is a regular there. If you lie and say it was yours, she will reveal that she already knew it was Ciri's idea, but will praise Geralt for supporting Ciri regardless of your answer. When you meet with Yennefer in Crippled Kate's, she will ask whose idea was it to go after Imlerith.
