Angela has left her kitty-cam on at her computer, so Oscar and Kevin get to watch when she arrives home, scolds Mr. Ash, and "comforts" Princess Lady. Which includes cleaning her with her tongue. "This is getting weird," Kevin says belatedly.
In the empty Nashua bullpen, Michael has found Holly's desk, with a yellow cardigan draped over the chair. Michael's so moved by this artifact that he cuts off half the sleeve to take with him. When he pushes her chair back, he bumps her mouse and shuts off the screensaver, revealing that her desktop wallpaper is Ed Grimley. Which is way more Holly than the yellow cardigan, if you ask me. That makes him smile through the tears, and then he notices an icon on her desktop that gets his attention: a Word document named "Dear Michael." Instead of opening it, Michael inserts his Flash drive keychain, which starts blinking. I could predict that Michael's accidentally stealing every file in Holly's computer, or worse, uploading his vacation photos with Jan or his Threat Level Midnight screenplay, but I'm just blown away that someone on TV actually uses Windows.
Angela returns to the office, surprised and maybe a bit embarrassed to see that her kitty-cam is still on. Oscar and Kevin claim ignorance of anything that may or may not have happened on it. "I was looking at pictures of food on my computer," Kevin claims. Angela settles down in her chair, and then coughs up a hairball. Which would be funny enough, except then Oscar does a little TH in which he tells us what just happened. It's not like The Office to have to explain a joke like that.
