Ok. The more I think about this page, the less... it makes sense. The idea is pretty simple. Thanks to this mix of Gariel and Barbera the Lady realizes she can spy on anybody anywhere within the city. Including sound.
But to get the sound she wants, she would not need Gabriel s log, only the address and then needs to find the right screen with the right camera or input the right camera in any of those screens.
Well. Ok. She might look up exactly this in the first panel. But if she does, she d basically have to flip through the whole telephone book to find a specific address within gabriels toilet paper log.
Ah. Ok. so. It somewhat makes sense.
I am also pretty sure that Gabriel herself doesnt need that log. She doesnt care who shes spying on - she cares for the big picture, a sense of the city. Maybe figuring out, what kind of crimes she needs to be equipped against. But... see German, you poor sod...
