There's a sealed apartment (sealed by the security shutters) you can get into through a ventilation duct that's up above an archway by the police station. In it is Cassian Valente's computer which is supposed to have some sort of advanced AI on it (according to her email). When you enter the apartment the AI says something that I didn't completely hear. The AI on the computer gives you three options toggle mood, open wall cabinets and return. Toggle mood and return don't seem to do anything though. Is this a plot line that was never developed? Or am I missing something?
