In the Anime & in the beginning of the Manga, Battosai looks like a diabolical killer. However, in the Manga, when Battossai meets Tomoe he acts normal.
One of the children at the dojo is named Shinta, which is Kenshin's birth named. In Samurai X: Trust, it was changed from Shinta to Kenshin, by Seijiro Hiko because it was too soft a name for a swordsman.
Sanosuke gives Kaoru castellas, which is a sponge cake popular among the Japanese public.
During this episode, Tae's eyes are closed, but in the beginning of the series, Tae's eyes are normal.
Spontaneous combustion like what happened with Shishio is impossible. If his body temperature was rendered unnaturally higher, his brain should have boiled in it's skull.
Kenshin forgot to tell his Master where the Aoiya was (like he couldn't follow the swath of destruction and find it... -ed.).
In this episode, they chose a different voice actor for Seta Soujiro.
The black tattoo marks around Anji's eyes are from Tsubaki's ashes.
Saito was never wearing the uniform hat, it was just the light from the explosion and shading of the drawing.
When Shishio fires the Armstrong cannon at Saito, Kenshin, and Sano, notice that in the still shot of Kenshin and Saito dodging the blast, the uniform hat of Saito's police officer attire appears (it is not present before or after this shot).
After Misao and the rest of the Oniwaban group make their appearance on the rooftop, it shows Kaoru and Yahiko. Yahiko's skin color has faded to match the skin color of the villagers.
Sano's headband turns purple because of the lighting.
While talking to Kenshin, Saito's "toothpick" is smoking.
While punching Kenshin, Sano's ribbon turns purple.
Juppongatana Roll Call
Elder Saizuchi, the short bald guy with the four whiskers, and his partner, Fuji, the giant who is only seen by his feet, are not mentioned in the roll call, although they are included in the group.
Chou is not able to attend.
Adding to the other point, the cigarette he has turns into a toothpick, than back and it is smoking, and then back into a smoking toothpick. Saitoh is smoking a toothpick.
In the CN dub of this episode, Saito's cigarette is replaced with a toothpick, but for a brief scene, the toothpick is a cigarette (they didn't edit the scene like they normally would).
The closing song goes back to T.M. Revolution's Heart of Sword ~Before Day Break~.
