Gabriel knows the basics of their layout. However, I am only giving him information he should logically know. Anyone who he directly meets turns into a source, and he knows all they know. Unless, of course, they find a way to shield their mind. Not tinfoil hats, but there is definitely a way.

I also find it amusing that Erik is bringing the one piece of information that might defeat Gabriel to an organization that will soon be in cooperation with Gabriel.
