It may still be a couple months before the new season of Heroes hits the airwaves, along with its subtitle of “Villains”, but we don’t have to wait quite so long for some new content – NBC will begin showing a three-webisode arc called Heroes: Going Postal online, and you can view a trailer. The webisodes follow Echo De Mille, a mailman with (what else?) an extraordinary ability. The first episode, “A Nifty Trick”, will debut on July 14th, with the other two following on subsequent Mondays.
