It really took too long for the team to discover who framed Tony. Legs were found with no body attached. All the forensic evidence pointed to Denozzo. Of course the one who figured it out was Abby. Very glad that Charles/Chuck is gone and we won't see him again. At the end it appears he would get Abby with his knife. But she has obviously turned the tables on him and has him bound with duct tape by the end of the show. The other extra characters were brought in to confuse the issue and distract from the real culprit. This is a good episode to find out who framed Tony because we know Tony would not murder anyone.
