It's no secret that Lydia has been working toward being promoted to YELLOW. It would make her life easier in many ways. It would also make Matt's life easier because neither of them would have to worry about being arrested for treason or something else like that. He worries about her wandering the halls, but then that's a common enough concern for him.

Matt doesn't blame her for not wanting to go to Citizen Improvement. It's dreary and uninspiring. There are many things he'd rather be doing with his time, but it's also an important thing for him to attend. When he heads to his room that night, he's tired (it's been an eventful day). He toys with the idea of sending Lydia a message or maybe going down to HQ once he's had a chance to clean up. He's got no idea about the GREEN jumpsuit so when he opens the door and steps inside, he's surprised to smell and hear someone else inside. The mechanical movements and the scent clue him in to the fact that it's probably Lydia and Gucci, but that doesn't make any sense.

"Lydia?" he says, his voice full of all that doubt and confusion.
