‘Arrow’ Season 3 Spoilers: Premiere Opens With Villain ‘Big Bad’ Seth; Episode 1 All Set After Concept Meeting?

"Arrow" season 3 spoilers point to one thing: the premiere will open with "big bad" Seth, as the writers of the show attended a concept meeting on for episode one.

Matt Webb Mitovich of TVLine dished out "Arrow" season 3 spoilers when he wrote about Seth.

"The casting for that role has since been tweaked, and he is now described as a 'shade of a man' with a quiet intensity, a 'criminal mastermind who whistles classical music' as he goes about his devious business," he wrote.

TVLine also noted rumors about Seth having reptilian eyes. "Whomever he is, he will be the Big Bad for the season opener," Mitovich added.

According to Cartermatt, based on the Twitter post of showrunner Marc Guggenheim, the writers held their first concept meeting on Friday, as the premiere date is scheduled for October 8.

"We worry that having so many different things to worry about and focus on could make things a little crazy," the website said. "But we were also worried about season 2 going in, and it turned out to be awesome."

Earlier, the producers revealed some "Arrow" season 3 spoilers when they introduced four new characters.

One character is Daniel who is an entrepreneur with a tragic past and working on "cutting-edge" technology. His past will drive him to embark on a vigilante justice. Daniel, who is a man in his 20s, will also be Oliver Queen's rival for Felicity Smoaks.

The website We Got This Covered  suggested that Daniel could be the "Blue Beetle," whom it described as a superhero who "relies on his genius intellect and advanced technology to fight crime."

Three more characters will be introduced such as Seth and Toshi-described as somebody similar to Slade Wilson. He is also the husband of Akiko, who also has some moves of her own.
