The creator seems to suddenly recall that three of the characters have super powers and a mysterious background whose mythology should be explored a little bit. Nothing really memorable or bad here, and still a solid if medium entry in the overall series with some funny moments and situations.
This is turning into one of those series where lot of really minor side characters pop up for no reason without any real reminder of their names or relevance to the series.
Oh so the psychic powers are finally relevant again! This series is ending up becoming very mediocre, with the rare laugh every now and then. But at least there's cool psychic powers now!
