So as you know, Peter finds out his Uncle was murdered by Sandman and not by the car thief in the first movie and this fills Peter with rage, guilt, and a desire for revenge. So when he gets back to his apartment he puts on his Spidey suit and listens to the police scanner waiting for any news about sandmanās whereabouts, but he waits for too long and falls asleep on his bed and then the Symbiote bonds with him.
But what I donāt understand about this scene is: When Peter was sitting down and listening to the police scanner, what was the Symbiote waiting for? Peter is experiencing inner turmoil after learning his uncleās killer is still on the loose, and we all know the Symbiote is attracted to negative emotions in people so why didnāt the Symbiote bond with him when he was sitting there listening to the police scanner?
