Beast Machines "Prometheus Unbound"

One of the episodes of Beast Machines was titled "Prometheus Unbound", a title whitch frankly I don't understand.
Time to show my Theater Geekieness...
Prometheus Unbound was originally the name of a play that was wrighten about the Titan Prometheus (as if that wasn't painfully obvious) who stole fire from the Gods and gave it to man. He was punished by Zeus and sentenced to spend eternity chained to rock while a voltcher came to eat his liver every day. Being an immortal his liver simply grows back every time but that doesn't mean he can't feel pain. He would later be freed by Zeus' half mortal son and some how... he knew this, apperently Prometheus was allso a Psychic.
Anyway Prometheus Unbound was a rewright of Prometheus Bound. I can't remember for sure who wrote it but sence I can't understand Bound I'm going to say Shakespear.
At any rate the reason I bring this up is because I studied both plays in high school and happen to discover that I still had the script for "Prometheus Unbound" and I'm absolutly shocked.
Anyway how did the Beast Machines episode end up with the title? It has absolutly nothing to do with anything even remotly simular to the Titan's story. http://www.bwtf.com/bm/tvshow/episodes/seasontwo/pu/
