We get the second episode post the Tohoku quake and tsunami which continues the trend of stripping the production down to the most basic elements. There is a bit more of a mix of songs performed so the theme is not as unified but again it is hard to critique these episodes considering the time they were filmed.
After this pair of episodes we return to the usual NHK Hall stage with the next month's episodes. IIRC, things slowly start going back to normal, and of course Johnny's needed to promote Kisumai as they were still set to debut. Plus they needed to get ready to debut the next FIVB group, Sexy Zone, as most of the members are finally around.
As much as tragic events like the Tohoku quake derail things at the end of the day life must go on. So like the rest of the Japanese entertainment industry Johnny's has to bounce back while doing what they can to support all needed relief efforts at the time.
