Millie Bobby Brown has responded to some viral fan theories relating to Stranger Things.

In a new interview with ET Online, Millie Bobby Brown talked about Enola Holmes 2 and Stranger Things 5. She responded to the theory that Eddie Munson –who was killed in season 4 — could return as Vecna’s second in command IN season 5.

“I mean, it’s a good fan theory,” Millie said while she refused to reveal more about the show’s fifth season.

She also addressed some of Stranger Things’ controversial deaths, including Billy, who was killed in season 3.

“Yeah, it sucks sometimes. I loved Billy. I loved Dacre Montgomery, who was killed off in season 3. I had a really good relationship with him, so for me, it was really hard to let go of that. And the same thing with Papa in this season. I had a really good relationship with Papa,” Brown continued. “I had a really good relationship with Matthew, and to let him go was really hard.”

The actress also revealed that she doesn’t know as much about the show’s plotlines as everyone thinks she does.

“I really don’t know,” Brown insisted. “People say, ‘Oh, you can’t say too much, like don’t spoil it.’ I’m like, ‘Oh no, I wish I could spoil it for you, I don’t know anything. They don’t tell me anything. You could go through my phone right now. They never text me. They never tell me anything, because they know that I talk to people like you, and they know that I’m gonna spill the deets.”

Millie Bobby Brown will be next seen in Enola Holmes 2 which will hit Netflix on Nov. 4.
