Mark's innie's watch that is in his locker shows 9:08 AM when he swaps it with his outie's watch which is showing roughly 9:06 AM.
What else is in Mark's locker:
The wall clock in Macrodata Refinement shows 9:10 AM when Mark walks in.
Dylan G says he's "about zero seconds" from completing the Tumwater file and that Petey needs to process it.
Mark opens the Dranesville file on his terminal.
The sorting buckets on Dylan's terminal are numbered 01, 02, 03, 04, and 05.
Irv says something about the perks being out of hand and that when they'd process a file in the old days they'd shake your hand and fill up the creamer.
Cobel informs Mark S that Petey is no longer with Lumon and he has been promoted to Macrodata Refinement department chief.
When Mark and Irv are in the training booth, Irv begins to say "Our last refiner, who was a woman, was--" and Mark finishes the sentence by saying "Carol. Dylan's old seat."
When Mark is leaving for the day, he takes of his lanyard as he's slowly driving out of the carpark and almost hits Helena who says "Maybe keep your eyes on the icy road"
