Asking Zane to watch something on television or play alone for some time, Anya went to her study. She frankly didn't want to disturb Jason on the first day of the new year but she couldn't help it.
During every mission, they always handled many criminal cases. Although Alvin's situation wasn't related to any of her missions, she couldn't help but guard up against Miles Johnson.
Using a mobile for a single call and deactivating it wasn't a simple thing to ignore. It was part of a crime.
After reporting everything to Jason, the latter was quiet for a few seconds and calmly declined Anya's plans. [Miles Johnson's actions are indeed questionable but don't forget he is a citizen of Country X and he is staying in Country X.] So his criminal activities go under Country X jurisdiction.
