The context of the following conversation is Addison fulfilled Alex's mission instead of them because Alex was not as capable an agent as Addison.:
Addison says This is the last time I want to step in for Alex.
The friend responds I guess  Alex should really ask for some more training on the missions.
Addison responds I think that would be a good idea because I won't always be around to save him.
The friend responds I guess I'll ask him to start working harder and taking things more seriously around here.
Addison responds sounds like a smart idea.
