Thanks to the help of his new human friend, Myau is at last reunited with his old human friend. That would be Alis and Odin, respectively. Odin has just been restored to normal from petrification. Myau had the special medicine needed to accomplish this, but could not open the bottle on his own. Teaming up with Alis turned out to be a really smart move for the feline. He certainly looks happy to have both of his friends together, eh?
Also, take note: the artists had the presence of mind to draw Myau without his trademark bottle hanging from his collar. Alis would be holding at the moment, so that is a nice attention to detail. It seems the bottle will be restored to the collar shortly after this scene, however.
