In the episode 4 season 1 of Homecoming there's a scene where Thomas asks Colin a few questions about the Homecoming project and Heidi. Thomas tells he found a client and will talk to him, and enters the elevator. Right after the door closes, Colin seems upset and just gazes at his shoes, and the shoelaces are undone.
Is there a metaphor here? What does this scene mean? Do the undone shoelaces represent something?
