I smash through the Looking Glass to find a safe. It requires Hacking Level 3, so I can’t hack it. He must keep his code somewhere around the room. His emails mention what I assume is his late wife, and the memories he has and is quickly losing of her. He seems obsessed with seeing her again, even if just in the virtual world, and is building a simulation of the Italian city where they met. His journal mentions her birthday over and over. He doesn’t want to forget it.
Her birthday is the code to the safe. He was storing useful upgrades.
