Luke Skywalker's story has come full circle since the original trilogy. Disney

Warning: Spoilers ahead for "Star Wars: The Last Jedi."

"The Last Jedi" ended with Luke Skywalker Force-projecting himself and then dying.

Writer JM McNab noticed that this parallels the way Luke's story began with a projection of Leia asking for help.

McNab's tweet has gone viral, bringing this gorgeous and heartbreaking revelation to fans.

"The Last Jedi" has been hailed as a masterful, though divisive, new take on the "Star Wars" franchise. Even months later, critics are still finding new ways director Rian Johnson brought thought and care to the beloved characters and their storylines.

At the end of "The Last Jedi," Luke Skywalker saved the Resistance fighters by Force-projecting himself onto the planet Crait and distracting Kylo Ren while they escaped. The effort of this last act killed Luke, and "The Last Jedi" ended with him disappearing and becoming one with the Force.

Writer JM McNab realized that this links back to the way Luke's story first began in "A New Hope."

"Just realized that Luke Skywalker's story begins with Leia sending a projection of herself asking for help, and ends with Luke sending a projection to help Leia," McNab tweeted on Wednesday.

The tweet and its accompanying images from "The Last Jedi" and "A New Hope" garnered over 10,000 retweets and 36,000 likes overnight.

McNab, who writes for Cracked.com and co-hosts the "Rewatchability" podcast, told INSIDER in an email that he's a big fan of "The Last Jedi."

"What I especially love about the movie is how it rewards thoughtful consideration and repeated viewings," McNab said. "I saw it multiple times in the theatre, but for some reason it wasn't until I was watching it on blu-ray at home that I happened to notice that parallel. "

The Luke/Leia projection connection immediately hit home for fans on Twitter, where minds were blown and tears were shed.

A screenshot of McNab's tweet also made its way to the "Star Wars" subreddit, where fans continued to geek out over this detail and its emotional meaning.

"The Last Jedi" director will likely continue wowing "Star Wars" fans with the new trilogy project he's working on for Disney.
