The freshman season of the show "This Is Us" registered as a hit among viewers who all are now wondering how patriarch Jack Pearson (Milo Ventimiglia) met his untimely death.

Fans do not have to wait long as this question will be answered. In a recent interview on "Larry King Now," Mandy Moore, who plays Jack's wife, Rebecca, confirmed that the way Jack died will be revealed early in the first episode of the second season.

Viewers will also get to learn about Jack's dark side in the new season. Jack was largely portrayed as a supportive, upstanding and caring man. He loved all his children equally and read them books before they went to sleep. However, things will not be all that smooth in the next season. The shortcomings of Jack will be put to the forefront.

Ventimiglia teased that Jack's flaws "might not be in the front of Jack's book, but... it doesn't mean the ripped pages aren't there."

After all, it was shown that Jack at one point, wanted to commit armed robbery before he met Rebecca. Also, it was hinted that he had a bit of a drinking problem when he got into a fight with Rebecca over her singing.
