Deadpool” star Ryan Reynolds recently penned an emotional farewell on his Facebook to a 13-year-old Canadian fan who he met through the Make-A-Wish Foundation. Reynolds had been visiting Connor McGrath for three years before the teenager’s battle with cancer came to an end earlier this week.

“Connor was 13. But this kid… He was smart. He was funny. And not just funny ‘for a kid’ – or funny ‘for a person battling something awful’. He had that… thing. That thing you see in great performers or comedy writers,” the actor wrote.

Reynolds called McGrath “Bubba” and McGrath would call Reynolds “Bubba2.” They met because McGrath loved Deadpool and he was the first person to see a rough cut of the film.

He added that before people blast him for showing an R-rated film to a 13-year old, “please know this kid knew more swear words than a British chef.”

“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,” wrote Reynolds.

Wade Wilson, the main character in “Deadpool,” is a cancer patient that undergoes an experimental cure. The cure somewhat succeeds but also turns him into the “Merc with a Mouth.”

Reynolds wished McGrath could have “stuck around a lot longer.” He said that in a way McGrath reminded him of the superhero.

“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,” he wrote.

The “Deadpool” star sent his condolences to the parents and family before signing off his emotional post with, “See ya down the road, Bubba.”

“Deadpool 2” is set to hit theaters in 2017.
