第0季第5集，在动画的结尾明确标有 scene 09ex 的字样，即这一集的命名应为scene 09ex。但在中国大陆境内的视频网站哔哩哔哩上，将这一集命名为EX5。（中国大陆内的其余网站均以09命名） 我的理解是这些并不冲突，S1E09是scene 09，那么scene 09ex意味着是scene 09的extra。而EX5是表示这是第五个Extra。 但不论怎样，从前到后的命名应当统一。故我将中文中的S0E05的命名继续更改为"scene 09ex"，以与前面的集数和动画中的画面统一。 In S0E05, at the end of the episode, clearly marked with "scene 09ex", which means this episode shoule be named as "scene 09ex". However, on the Chinese video sites —— Bilibili, this episode is named as "EX5".( All other site in China named this episode as "09") in my opinion, this two do not conflict. S1E09 is "scene 09".So, "scene 09ex" means this episode is the EXTRA of "scene 09", and the "EX5" means that this is the 5th EXTRA VIDEO of this Animation. But no matter what, the name of the episode number should be unified. Therefore, I continued to change the name of S0E05 in Chinese to "scene 09ex" to be unified with the previous episodes' name and the screen in the animation.
