Originally posted by InhumanIt was kinda a CIS moment. Joker had setup a bomb and had every intention of killing himself and everyone in the city, Cassidy became nervous because of this and the result weakened his control over the symbiot to the point where he could neither hold Spiderman or Batman. In this weakened state they were able to take him out.
Oh that sly joker....seriously, how did the joker interfere? You have the scan of the next page?
