The seal breaks

Seeing spider die , something inside Scorpio snapped as he wailed and went on a killing spree , chopping everyone who stood in his way into a bloody carved up mess.

The four of them were childhood friends and had gone through various life and death situations together , however now spider was dead , and the other three could not bear the loss.

The most rational one in the group , the leader Serpent could not piece the information properly , as he estimated that there must be a hidden expert inside the carriage.

Even though the reports about Percy and Ronan suggested that the two were peerless geniuses , Serpents logical brain refused to beleive that a 7 year old kid could master a terrifying move like the one that decapitated spider , and had to be the work of a hidden expert.
