Personally this bored me as I do not find Four Tops and Jimmy Mackey that interesting on their own. Sometimes they can be but it is hit or miss for me and this time it is a miss.
We have an odd combination for the end song with Yamashita Tomohisa with the three Ks of K.K.Kity. Though I guess if you really wanted to you could theorize that Johnny's was perhaps testing to see how Yamapi and those three would sound/look together to prepare for NEWS' debut in about a year's time from then.
Overall an okay episode. While there were things hear and there I was happy to see and enjoyed there was also quite a bit I just did not care for.
Still rather excited to have this episode done and be one episode closer to reaching the next season.
