“Attack on Titan” Season 2 will not premiere until next year. Fans have been itching to know what happens to their favorite trainees next. What does the next installment of this anime series have in store for them?

An official announcement has yet to be made by the production department itself. But according to Movie News Guide, a trailer for Season 2 has been leaked. The clip reportedly featured Hange ordering to kill a Titan. The film blog suggests that this might mean that the next season’s storyline has already been set.

The leaked trailer also showed Hange doubting her decision to have the Titan killed. Her doubt would reportedly stem from her mistrust of Pastor Nick, who seems too keen on getting rid of the Titan. Does Hange have grounds to doubt Pastor Nick? Who was the Titan she had killed anyway? Was she correct in deciding to kill him? Movie News Guide is a little unsure. Fans might have to wait for the show’s return to find out.

Meanwhile, according to the Christian Times, the anime’s next season might just feature the origin story of the Titans. The rumored story arc could finally confirm where the show’s main antagonists actually came from. Christian Times also reports that a couple of new characters are coming in next season. These characters include Captain Kenny Ackerman, Uri Reiss, Rod Reiss, Frieda Reiss, and the Beast Titan.

Another rumored plotline would involve the noble family of Reiss. Christian Times claims that Attack on Titan Season 2 will explore the “corrupt ways of the king and his eventual decline.”

When can fans expect the show’s comeback? If rumors are proven true, “Attack on Titan” Season 2 is set  to return to the small screen in the second quarter of 2017. However, this has yet to be confirmed. Stay tuned for updates.
