George R.R. Martin has said the ending of his book series “A Song of Fire And Ice,” which the show “Game of Thrones” is based on, will be bittersweet.

And in a now-viral thread that Dan Fogelman, creator of “This is Us,” recently shared on Twitter about his friend and “Game of Thrones” superfan Alex Hanan, it seems that life imitates art.

“It was the stuff that really only happens in a movie,” Fogelman told HuffPost. “But on top of that, for Alex’s sheer larger-than-life personality to have willed the connection to happen … it made it all a little magical.”

In honor of the HBO hit show’s eighth and final season on Sunday, Fogelman tweeted about Hanan, whom he described as “handsome and charming as hell, with the best head of hair you’ve ever seen” and also “obsessed w Game of Thrones like no one you’ve ever known.”

Hanan loved to give away spoilers about the show, Fogelman told HuffPost.

“He would announce that he wasn’t going to tell you something, then tell you because he couldn’t help it,” he said.

Fogelman began his story by explaining that he and Hanan were meeting up to see Bruce Springsteen’s Broadway show about a year ago. Hanan got to the show early and called Fogelman while he was on his way over in a cab.
