Okay, so I know we all picked up on Thomas's over shirt at the end of WTIT being green, representative of Remus's lingering effects on him and showing that Remus was very much still with him even though we don't see him in the rest of the episode, something else caught my eye this time though.
Logan has been trying all day to get Thomas focused and to complete the tasks on his to-do list, all of which Remus has been interrupting, then of course he runs out to meet Nico, completely disregarding Logan's plans. When this happens
Thomas not only changes his dark blue hoodie for a green button down, he also ditches the space themed for a blank grey tee.
Space and Logan are pretty closely tied together, from his casual photo shot to his suggesting Thomas take an astronomy course. Thomas wearing the Space themed shirt is, in my mind, more symbolic of Logan's influence than the color of his hoodie, (the hoodie itself is very representative of Virgil, but that's another post) so when he takes off the space themed shirt, he's very much casting off Logan's influence and desire to accomplish the chores around the house.
