Rin: None of this would have been possible without your assistance. Even so...

You were ordered to simply observe, NOT to infiltrate. If you had simply went home, it would have happened anyway - we were cleared to have Hayato inspect the place when I received Sachiko's call. 

You do NOT have the training of a Rogue, nor do you have the experience necessary for these sorts of things. Dealers may have weapons or hired thugs to protect them. You could have gotten hurt, or WORSE!
