Rupert Grint made one healthcare worker’s night when he surprised her during a virtual chat to thank her for exemplifying “Gryffindor behavior” amid the coronavirus (COVID-19) pandemic.

The Harry Potter alum, 31, appeared alongside actress Miriam Margolyes, who played Professor Sprout in the Harry Potter film franchise during the One World: Together at Home special in the U.K. on Sunday to show his appreciation for Sam Halliwell, a 33-year-old midwife working on the frontlines of the health crisis at Birmingham Women’s Hospital in England.

“Hearing your story is just insane,” Grint told Halliwell, Metro reported. “The sacrifices that you make is truly inspiring. It’s very Gryffindor behavior. Thank you so much.”

Halliwell has been self-isolating at a hotel during the coronavirus outbreak to not risk infecting her immunocompromised husband at home.

Also during the stream, Margolyes, 78, caught up with Grint since their time filming the Harry Potter series together. “You were just a little boy when I saw you, you’ve turned out to be a very handsome young man,” she told the star, according to the Daily Mail.

Grint is currently expecting his first child with longtime love Georgia Groome.

“Rupert Grint and Georgia Groome are excited to announce they are expecting a baby and would please ask for privacy at this time,” a rep for the parents-to-be confirmed to PEOPLE after Groome, 28, was spotted showing off her baby bump with Grint during an outing in London.

The couple, who have reportedly been dating since 2011 but kept their relationship out of the spotlight, were seen stocking up on supplies earlier this month amid the coronavirus lockdown. During the outing, both were dressed casually, with Grint wearing a dark jacket and a green cap. Groome, who’s best known for her starring role in the 2008 film Angus, Thongs and Perfect Snogging, wore a black T-shirt and leggings.

Grint, who stars in the Apple TV+ series Servant, previously indicated his interest in starting a family.

“Turning 30 felt strange. It just doesn’t feel like I’m there yet and I don’t know what the future holds,” he told The Guardian in 2018. “I’m just going to go with the flow, keep playing interesting characters, and see what happens. I’d like to settle down and have kids soon.”

The actor also playfully toyed with the idea of naming a future son after the beloved Harry Potter character he portrayed in the blockbuster movies, Ron Weasley.

“If I had a son, would I call him Ron?” he quipped. “It’s quite a good name, but probably not. And Grint’s a tough name to pair a one-syllable first name with.”
