Ryan Reynolds has shared a story on his Facebook page about a young "Deadpool" fan that he had the honor of meeting through the Make-A-Wish foundation. Connor McGrath, a 13-year-old in Edmondton, Alberta, lost his battle with cancer two nights ago, and Reynolds penned an open letter describing the too brief period of time he got to spend with the superfan.

"It was the Make-A-Wish Foundation that brought us together," wrote Reynolds. "I can't thank them enough. Seriously. Thank you. Because of his wish, Connor was the first person to see 'Deadpool.' I traveled up to Edmonton, Alberta to surprise him with a rough cut of the film. There were still huge sections with wires we hadn't yet painted out, jokes which weren't working (and still aren't) and green screens. Connor didn't seem to mind. And I'd never felt luckier to get to be Wade Wilson."

Reynolds visited Connor twice, and exchanged text messages in-between visits, getting to know the kid that he said "knew more swear words than a British chef."

"We met because he loved Deadpool. In a certain sense he was Deadpool. Or, at least everything Deadpool aspires to be; balancing pain, fearlessness, love and a filthy (filthy!) sense of humor in one body. I wish he could've stuck around a lot longer."

You can read all of Reynolds' letter below. Reynolds also urges people to donate to Make-A-Wish, the organization that facilitated their meeting.
