Eventually, Add does come to the conclusion that maybe breaking into the apartments of equally confused people isn't the best way to address this situation. So, he takes his investigation elsewhere. For now.

There are computers at the check-in counter of the apartment lobby—well, not anymore. One computer is now in several hundred pieces, all scattered around the counter in neat little piles. They're "organized", but in a way only Add would be able to decipher, most likely. At least he seems to know what he's doing? The more useful parts are set aside, as well as anything that might contain recoverable data. If he just had a way to access it...

He's completely absorbed in his task, muttering to himself as he carefully examines each individual circuit in detail. That said, he's not so absorbed he won't yell at anyone who tries to touch his work station—he won't allow even one tiny screw being moved out of place.
