"Attack on Titan" season 2 is going to give more screen time to Ymir and the other Titan shifters.

Reports say that Ymir's secret is what will lead to the ultimate end of the series. Though it remains to be seen if his knowledge is weighty enough to give an end to the "Attack on Titan" series, fans believe that her character will reveal much about the existence of Titans.

Series creator Hajime Isayama promised that season 2 will feature Ymir more to give viewers a deeper understanding of the origin of Titans. A leaked video of "Attack on Titan" season 2 also revealed that Pastor Nick also has some hidden knowledge to divulge about their existence.

The leaked trailer is currently making the rounds online, and it shows a new Titan seemingly mortared on a wall. The video which allegedly shows scenes in the upcoming installment now has over two million views and shows a lot of Hange and bits of Eren.

In the trailer, a Titan's face that is protruding from the wall faces Hange. And while Hange is not sure about what he should do to the Titan, Pastor Nick instructs him to kill the enemy without ado. The video also shows Hange trying to get more detailed answers from Pastor Nick about the origin of Titans but ultimately giving up after the pastor insists on keeping his mouth zipped.

The end of the clip shows Eren waking up from sleep and sitting up in bed.

"Attack on Titan" season 2 is expected to premiere in early 2017.
