It had been two weeks since I went to the border and watched for Olivia from afar. When Raphael told me that Olivia would go to the border, I didn't go there right away. Instead, I went to other villages to distract my family.
In those two weeks, I witnessed how Olivia helped the army. She used her knowledge about poison to reduce the effect of the poison on the knights' body. Thanks to her, the army could survive longer than my family expected. She also slowly found and killed every spies planted by family.
Her action actually made me worry since if the spies reported the condition my family would notice her. Even though I helped her silently by telling Raphael who were my family spies.
