Clip #13 (which “fills in the blanks” of episode 17 of The Midnight Horror Show--and was part 2 of their Friday the 13th retrospect) was played on episode 21.
Summery: In this clip I school Danny on two characters from part 6 (Jason Lives), I take a guess as to the name of the town that Crystal Lake is located, I again school Danny on two characters from part 9 (Jason Goes to Hell), and discover the plot to the Friday the 13th: Abuser and the Abused comic.
