Katrina looks up at Duke, and thanks to him, "Mr. Wilson, thank you for telling me all this."
If Duke didn't come over particularly to tell her the truth about Aaron's engagement...
She would have no access to the truth all her life and secretly leave away, thinking that Aaron fell in love with another woman.
At least now...
She knows that he only agreed to engage Miss Johnson under duress.
At least now he doesn't fall in love with another woman.
That means she still has a chance, doesn't it?
Such deep feelings have infiltrated into her blood and breathing, and she really can't give it up frankly.
So, this time she has to fight for that for the last time and doesn't give in easily.
When she was with Marcellus, Aaron also didn't give up and pursue her persistently.
What Aaron could do, she could do too.
The more she thinks about it, the more Katrina solidifies her idea.
Duke is relieved when Katrina agrees.
