Original Commentary
Because unlike Brisbane, Kimberly has other responsibilties. If she's not doing her job, then Patrick, Richard and Sinclair have to make up for it. Brisbane's responsibilities are fairly undefined. We know he delivers mail, but he can get someone else to do that (and even if he can't, it doesn't take that long). Anyhow, I just wanted to point that out and show how Kimberly is aggressively filling the power vacuum that has been created - Terrence

Modern Commentary
This is Wednesday. You can't see what Kimberly's wearing here so it's less obvious, but trust me. The biggest clue is that Patrick says Kimberly hasn't been in her office for the last few days. If it were still Tuesday, that wouldn't be plural.

I considered putting little captions in the upper left when a new day starts but it seemed unnecessary. - Terrence
