Fate would have it so the Spider-Mugger actually mugs Peter Parker. Not able to use his powers in front of witnesses, Peter has no choice but to hand over his wallet and web-shooter (which the mugger assumes is a watch). Peter then gives chase to the mugger but is unable to catch him. He does manage to stick a spider-tracer on him.
Later, when Lou realizes he mugged Spider-Man, he tries getting his wallet back from his fencer. When he doesn't listen to Lou, he tries using the webbing on him. This just buys him a ticket to the morgue. Upon investigation, the spider-tracer is found.
Things don't look so good for Lou or Spider-Man.
