Summary:

They are both facing the doors when they open, holding their suitcases like respectable people, looking only moderately flustered. Kowalski holds the elevator door politely for the woman waiting with a stroller. They do not sprint to Cooper’s door. There is no fumbling with keys. They are as calm and dignified as Don Lockwood at a premiere.

They both stop trying to fake indifference as soon as the door shuts.
