In this episode a lot of the past is dug up, literally. Billy Quizboy finds a mysterious message hidden in an old episode of the Rusty Venture cartoon that leads him to a buried box next to Brock Samson's room. The contents of the box divulge the secrets of the Guild of Calamitous Intent, the death of Dr. Jonas Venture Sr., and the entire purpose of why Brock was assigned to protect the Venture Family.
The Guild crest seen in the zeppelin contains both the sword in the contemporary O.S.I. crest as well as the dragon in the Guild of Calamitous Intent crest, possibly suggesting that both organizations might have been one in the same in the past but split into the two opposing agencies which they are now.
