For starters, Millie said it's much different than her close-knit friendship with her Stranger Things cast mates.
"With Henry, it feels like a real adult relationship. Like a really healthy one," Millie said.
"[The friendship is] one that we have terms and conditions," she continued. "I know Henry. He has terms and conditions with me."
"I'm not allowed to ask about his personal life. It's like, 'Millie, shut up. No.' And I'm like 'Understood.'"
"Whereas with the Stranger Things kids, it's different," she added. "There's no boundaries because it's like we're all siblings. But with Henry, he's very strict with me, which I appreciate."
"So, for him, it must be completely different. I have a sister, a brother, and an older brother. So, I'm very much used to that kind of dynamic," Millie said.
"I had to implement a lot of that into my relationship with Henry offscreen and onscreen and just pull him out of his comfort zone."
Enola Holmes 2 director, Harry Bradbeer, corroborated this in the Deadline interview. "[Henry] has a very rational approach, but is learning more and more to have fun and to be spontaneous," he said.
"And of course, Millie and he had this very interesting, enjoyable dynamic where they’re always poking at each other. And Millie tickles him up a little bit and surprises him. And he goes with it."
In conclusion, we stan a healthy friendship with boundaries — especially in Hollywood. You can read the full interview here.
