"Next week's episode is a big episode," Fogelman said when asked about Jack's death. The full story will play out over a number of episodes -- into other seasons -- but on the heels of the announcement that the show has been renewed for two more season, Fogelman assured fans the series has been fully mapped out -- and there's a lot of story to tell. [...] again, something big is happening next week -- following a back-to-basics episode that took viewers back to the birth of the Pearson kids, as well as the decision to adopt Randall, that kicked off the hit show. Slowly but surely, he said, we'll learn when and how Jack died -- and then, presumably, how his wife Rebecca Pearson (Mandy Moore) ends up with Jack's best friend Miguel (Jon Huertas) -- but that will unravael over "many many episodes," Fogleman said.
