In the Campaign Mission Wrench in the Works you'll find actress and Ubisoft press conference spokesperson, Aisha Tyler, talking to another NPC.

You can also see Aisha in what appears to be a hotel room or lounge talking on the phone. In the City Hall building in the Loop district, there is a City Hotspot. Nearby is an unmarked 'intrude' console which Aiden can hack. Doing so accesses a camera where you can watch Aisha on the phone telling someone not to worry about her being followed, and humourously discussing her fart.
