'The Master Return' is a fair episode. Serrator has sent his plans in motion. The head villain chance coming to Earth to stop him. That seal must be weakening, if he was able to get to Earth, if it for a short time. He was able to injure Jayden before having to return to the Sando River. I also like that Bulk and Spike made an appearance in this episode. They meet Mentor, who remind them what happen to them on their last visit to the Samurai Ranger's hideout.
