Garner visited Henry for about 10 minutes as he was getting his second-to-last chemotherapy treatment, and his mother, Carrie Shepherd, described the A-list star to ET as "very down to earth, very kind, has a big heart and very genuine."
"We didn't know we were going to meet her, it was a complete surprise," she further shared. "She, like me, is a mother of three. It was an honor to meet her. She's a big celebrity but more than that, just a nice, kind and warm person."
Henry said he was "surprised" by Garner's unexpected visit, where they talked about making movies in Atlanta, and couldn't help but gush about the actress, saying "she was very nice." Henry also gave an update on his treatment, saying he "was excited about his last chemo treatment [Friday]."
