'Stranger Things' Actress Francesca Reale Explains How They Shot Key Season 3 Scene [SPOILERS]

This story includes spoilers for 'Stranger Things' Season 3.

Stranger Things finally returned for its third season this week, after almost two years of fans waiting. Thankfully, the new episodes were definitely worth the long break, and it looks like most of us are just beginning to process what we saw. David Harbour was right when he said the only word to describe the season is "epic."

One of the more shocking moments which occurred in the first half of the season saw Eleven using her powers to try and figure out where Heather the lifeguard was. Although Max warned El that she might see weird things when she went into the Void to find Billy Hargrove, the telepath certainly was not ready for what she saw when conjuring up his missing coworker. In the scene, Eleven sees a bathtub of ice and cautiously walks up to it, only to be terrified when Heather pops up and begs for her help. Almost instantly, however, she is pulled back underwater and cannot be saved.

Francesca Reale, the Stranger Things newcomer who plays Heather, just dished on how they filmed that intense scene, and how great it was to have Millie Bobby Brown (who plays Eleven) there with her.

"It's so interesting, because people have been asking what was my favorite part of shooting, and that was actually one of my favorite parts but I haven't been able to talk about it. It's such a big spoiler," Reale told CinemaBlend. "But we had to do it on two different days and there was this day where it was just me literally in a tub, just drowning myself essentially. It was all these fake silicon ice cubes, and believe me those were like sand and found their new homes literally everywhere on my person. My hair! Everywhere. It was essentially just me and Millie [Bobby Brown] just yelling at each other and me drowning myself. And Millie was such a sport because she had just come back from her knee injury at the time. She was such a sport for being there and actually acting with me instead of using a double, because she knew it would be more helpful for me."

Capturing the drowning part itself seems like it was just as intense as the final scene as we saw it. Reale went on to recall how they were able to drag her down into the tub without using special effects, explaining:

"And doing the drowning was actually in a pool with a black bottom, which was terrifying for me because I hate any body of water that has a black bottom. And they had this amazing mechanism that attached to my foot, and whenever I was ready, I would go down underwater and the mechanism would tug me down. And then our beautiful, wonderful, talented director Shawn Levy was like, 'Francesca, it's great, but I need you to hold your arms out and not move them so there are no bubbles. Keep your eyes wide open, as wide open as you can, and scream but not produce any bubbles. I know that's a tough ask, but I need you to try.' It was incredibly hard! But it was one of the most fun stunt-esque things that I've got to do in my career so far. I hope to do more in the future."

Although we knew close to nothing about Heather prior to this scene, that didn't take away how powerful it was to watch, and only made us care about the character more. Even considering how big a season this was, the bathtub scene is definitely at the top of the list of craziest moments to go down.
