Saito stepping in to protect Chizuru from a belligerent ronin, only to get completely distracted by how pretty she looks dressed up as a geiko. Cue several hilarious minutes of Saito, wearing the same deadpan expression as always, trying to express this to her - while simultaneously and effortlessly beating down the ronin with a series of Offhand Backhands each time he tries to intrude.
Chizuru: We could talk about it later, but right now...
Saito: No, it would not serve its purpose if it is not now.
- At the end of the episode, he finally manages to say it, but by that point the moment is long gone and Chizuru, distracted by other subjects, thinks he's talking about what Hijikata would look like with a beard.
