Plec said, "It's both a gift and a burden to be able to control the ending of a series. Many shows are not lucky enough to have a hand in deciding when the end has come."
She went on to ask fans to "join us at Comic-Con and as we move ahead with our final season of The Originals".
The Originals panel will take place on Saturday, July 22, at 12 p.m. PT at the Indigo Ballroom in the Hilton San Diego Bayfront Hotel.
