Catherine's presence tests Annabelle's patience. What she feared, had happened. It is very obvious that Catherine wants to ensnare Albert's heart. Catherine stole several times to go alone with Albert to tour the castle and that irritated Annabelle quite a bit.
"Where have you been with Catherine this afternoon?" Annabelle asked her husband.
"What kind of question is that? Are you jealous of your husband?" Albert again asked Annabelle.
"Of course I'm jealous. I'm pretty sure that woman came here with one purpose."
"What's that goal?"
"She's here to ensnare you, to take you from me."
Albert laughed at Annabelle's words which seemed absurd, but Albert could understand with Annabelle's jealousy.
