Other mistake: In this episode, they have a leak in the roof. Yet, the house is a two story house with an attic. So it should not be able to leak into the living room. Also, when Carl and Eddie go up to fix the roof, Eddie falls through the roof and ends up on the living room couch. Again, two story house with attic. Should not happen.
Other mistake: When calling their next patient, the nurses look at the small screen to find out what number is next. After Mr. Bean has rotated the device, however, a nurse calls number 92 before the screen displays the 9. (00:06:22)

Other mistake: Throughout the episode, the English translation greatly misses the joke when it comes to the nature of the fight; the referee keeps replying to Akane's protests "The tools she has are legal" or "she is using legal tools", while the real catch in the rules (and correct translation) would be "using tools is legal", which taken literally means that any tool, even the obviously lethal and unplanned ones, are fair to use, anything goes as long as it's a foreign object and not a bodypart.
