Twitter calls for Mandy Moore to win an Emmy for penultimate episode of 'This Is Us'

It's been six incredible seasons of This Is Us and, during the penultimate episode Tuesday night, which Mandy Moore recently said made her throw up over when she read the script, had viewers on social media both sobbing and praising the brilliant, but devastating episode.

The episode, which was dedicated to saying goodbye to the Pearson family matriarch, Rebecca, was full of heart-wrenchingly beautiful moments that only This Is Us could deliver.

Half of the episode took place on a fancy train, where viewers were taken on a ride inside of Rebecca's mind leading up to her death. On the train, Rebecca got to say goodbye to every member of her family, including every actor who played the characters throughout the years, before she ultimately reached the caboose – the final car on the train that was her life.

It was there on the train that William, Randall's birth father, guided her while sharing words of wisdom like, "The way I see it, if something makes you sad when it ends, it must have been pretty wonderful when it was happening. Truth be told, I've always felt it a bit lazy to just think of the world as sad, because so much of it is. Because everything ends. Everything dies. But if you step back. If you step back and look at the whole picture. If you're brave enough to allow yourself the gift of a really wide perspective. If you do that, you'll see that the end is not sad, Rebecca. It's just the start of the next incredibly beautiful thing."

And in the caboose, which symbolized the end of her life, Rebecca was reunited with Jack, which was, hands down, the biggest tear-jerking moment of the night.

The episode was truly incredible. So it was no surprise that longtime fans of the show took to social media Tuesday to praise the This Is Us penultimate episode, with many calling it "the best hour of television" they have ever watched.
