Jiraiya: So. You want to say, that you decided to delay an important courier mission, to check the corruption of my intelligence network. The network which I have built and maintained over the years, which you only got a few shallow contacts from.
Hazō: Um...
Jiraiya: Not only that, you decided to conduct this mission without your team's only infiltration specialist, and under the command of a leader you hadn't even known until now.
Hazō: That is...
Jiraiya: All which lead to you blowing the cover and brain of my main contact in Sand, who was my cousin, I might add. Also, your "investigation" alerted local authorities, leading to yet another diplomatic incident.
Hazō: Ah...
Jiraiya: And on top of that, when "checking his coworkers integrity", our esteemed college announced that "those stinkers are full of crap" and decided to level the whole building he was in. The building, which I might add, contained half of Sand's secret documents we managed to gather thus far. The building which also contained several priceless potteries, ones dating from the time of Sage of Six Paths?
Hazō: Ummm... yes?
Jiraiya: ...
Hazō: ...
Jiraiya: Kid. Running a spy network is a very delicate job. Just leave handling it to the professionals.
That should sum up what I think about trying to fix a professionals work.
