One more question has been answered on the popular series, "This is Us" and it is somehow melancholic. It was during the Tuesday episode when the reason behind the death of Jack was spoken about. There was one tangible answer that was already given a clue on the demise of Jack and unto which the mystery of his death was unknown for a long time.

It was remembered that Jack died when the kids were just teenagers together with Kevin, Kate, and Randall. In the episode that was shown, Kate has took part in a drum-therapy class at an adult weight-loss camp and it was through her teacher's instruction wherein she has to dig deeper into one of her heart breaking memories from the past, her father's death.

According to ET Online, at first it was unclear when the funeral took place with Kate's memory. There were memories flashing through Kate's which includes Rebecca's coveted moon necklace from Jack, the big three's polished dress shoes and a framed photo of Jack, and the urn containing ashes.

There were three popular theories on Jack's death. According to the series creator Dan Fogelman, there was a hinge in the family and it will be interesting for the future seasons since they'll be showing the viewers on where that hinge was.

Meanwhile, it will be a huge twist for the fans about the mystery of Jack's death and Mandy Moore is somehow worried about it. Viewers will be getting a new piece of information into the most recent episodes while Moore or Rebecca spoke about the pivotal scenes and how it means to the Pearson's family.

Viewers are still curious on Jack's demise though in the recent episode, it was revealed that his kids were teens during the funeral and Moore was glad that clues were getting clearer. Further, Moore added that she's not sure if fans will be ready about the forthcoming death reveal but somehow, she hopes that this will satisfy the need to know when, how and what, US Magazine reported.
