If you are not caught up on NBC's This Is Us you might stop reading now. No, seriously, do it now.

*Spoilers Ahead*

On NBC's This Is U we're about to learn the details of Jack's death. We know a crockpot start's the fire and that, assumingly, Kevin never got to have the important phone conversation with his dad because Kev's a little jerkface. So, what (or who) killed Jack?

Theory #1: Is it Kate's fault?

Interesting points made by Lil Zim, but my wife has a different idea - and I agree with her.

Theory #2: "Kevin?!"

The only way we will ever know what happens to Jack is by watching This Is Us on NBC after Super Bowl LII.
