I am aware that the movie was its own canon, and just as well really. I just feel that Mordant just appeared with no establishment and had to be accepted for just being there.

I think nowadays, things like this show why some films have prequel novels/comics to cover up such things.
Can't remember the colouring book in great detail, but remember that's where I picked up on the cousin thing. It was all pictures and narrative text at the bottom of the pages.
Skull's appearance in the Christmas special would have really made that episode and filled an obvious gap. He could have at least had a mention. When is the next PR:S set to air? Looking forward to the new Super Samurai formula.
