This Is Us Fans React to Emotional Episode That Revealed Rebecca's Fate: 'Never Cried Like This'

Warning: This article contains spoilers from Tuesday's episode of This Is Us.

Fans are emotionally recovering after the latest episode of This Is Us.

As viewers know, Tuesday's episode brought fans on a tear-filled journey through the final hours of the life of Rebecca Pearson (Mandy Moore).

There were appearances from two series favorites, William (Ron Cephas Jones) and Dr. Nathan "K" Katowsky (Gerald McRaney), as well as some emotional goodbyes from Rebecca's family, including Beth Pearson (Susan Kelechi Watson) and Toby Damon (Chris Sullivan).

Ultimately, Rebecca hung on long enough so that all three of her kids could say goodbye, and then, with The Big Three by her side, she drifted off into a peaceful, eternal sleep, where she was joined by her late husband, Jack Pearson (Milo Ventimiglia).

While the episode promised to be an emotional one — even making Moore throw up upon reading the script — fans made it clear on social media that nothing could've prepared them for what unfolded.

"There is something so beautiful about William being Rebecca's guide," tweeted one person.

Fans were also left sobbing after Rebecca had a heartfelt conversation with Dr. K in the train and when the storyline with Marcus' family came together and connected with the Pearsons.

"Everything in the episode was beautiful and touching, but the conversation with Dr. K just had me bawling and it never stopped," tweeted one person.

"The connection with Marcus' dad and Jack and then future Marcus and Alzheimer's," wrote one fan with clapping hand emojis. "Favorite aspect of watching this show are the connections #ThisIsUs"

"This ending truly was perfectly written. Jack died in the same hospital at the same time Marcus was coding and now is responsible for pioneering Alzheimer's treatments," tweeted another person.
