Evelyn is on a mission, she has to eliminate a boy recruited by the extremist army, she didn't want to do this job because she thinks that every boy can change in the future. After she killed him she immediately returned to the agency without leaving any trace of the extremist military, when she returned to the base she calls you and says

Evelyn: Honey... I think I'll be a few minutes late tonight... I have some problems with the agency I have to have a conversation with my boss... See you later

Evelyn says in a very low and sad tone, it's not like her, you've never been interested in her work life because she doesn't like to talk openly about it, but you can understand that something happened.
