...in the "Episode With No Name", where the three Infected Guardians and Turbo were searching for Guardian 452...they all had scanned for and registered Glitch on their scans. Glitch is Bob's keytool and Bob is also Guardian 452. When the Infected Guardians tracked down where Matrix was, they kept calling him Guardian 452 by mistake...they thought Matrix was Bob. Turbo saw that Matrix wasn't Bob and demanded to know where Guardian 452 was. Matrix didn't assume the title/name of Guardian 452...if anything he kept insisting on being called a Renegade.
