Ella Purnell's role on the Yellowjackets just got an emotional update, and it's a huge relief after Jackie's death in season one

Jackie has been dead since Yellow Jackets Season 1, but she has continued to appear since then, and a new trailer confirmed that Ella Purnell will still be on the show in Season 3. Yellow Jackets Ingeniously used its dual timelines to foreshadow important plot events. In the first season, the most shocking use of this technique was teasing Jackie's dark fate. Jackie didn't have an adult counterpart in the current timeline, so it was obvious that something terrible would happen to her in the '90s timeline — but it wasn't clear what.

At the end of Season 1, Jackie had a huge fight with Shauna and was ordered to sleep outside the cabin. However, the next morning, to Shauna's horror, they discovered that it had snowed all night and Jackie froze to death. Jackie's death caused Shauna immense guilt throughout Season 2, as she was technically responsible, and that guilt manifested itself when Jackie's spirit appeared to Shauna in disturbing visions. Based on the latest trailer for Yellow Jackets' in season three, it seems that Shauna still hasn't escaped these visions.

New Yellowjackets Season 3 Teaser Confirms Ella Purnell's Return as Jackie

Shauna gets another glimpse of Jackie in the Season 3 trailer

In the new Yellow Jackets Season 3 trailer, Shauna sees another disturbing vision of Jackie. Shauna appears to be in a dark public bathroom, having a vision of Jackie sitting in a stall and looking at her. It's a blink-and-you'll-miss-it moment, but it's unmistakably Jackie with a stunned Shauna looking back at her. Jackie is covered by a quote from a film critic The New York Times praising the show for being “beautifully disturbed,” but it’s clearly her. This suggests that Shauna's visions of Jackie will continue to haunt her throughout season three.

It was unclear whether Purnell would return to Yellow Jackets season 3. Not only has Jackie been dead for over a season; Purnell's career is taking off and she has become one of Hollywood's most sought-after stars. She took on other leading roles in TV shows, such as Lucy MacLean in Precipitation and Rhiannon Lewis in Sweet peaboth renewed for a second season. But it appears that Purnell has found room in his schedule for a Yellow Jackets return. Appearing in a few guilt-ridden visions probably only takes a few days of filming.

Ella Purnell's Yellowjackets Season 3 Return Hints She Will Continue to Recur Throughout the Show

Purnell will likely remain until the end of the series

If Purnell is back as Jackie in Yellow Jackets season 3, so it probably means she'll stick around for the rest of the entire series. Jackie's return in Season 2 made sense since she had just died and teenage Shauna was dealing with an incredible amount of guilt over her death. Having Jackie appear in visions was a great way to kill two birds with one stone: visualize the guilt Shauna is feeling and keep one of the show's best actors around for a few more episodes.

However, it remains to be seen whether this would continue through Season 3 and beyond. Given that she's back in Season 3, and is in the current timeline with the adult Shauna hallucinating her, it seems like Purnell can be expected to appear throughout the rest of the show. His appearance in season three – and in Shauna's adult life, years after they escaped the jungle – means there is no end to these visions; Shauna is stuck with them forever (and Purnell will be on the show forever).

What the return of Jackie's vision in the current timeline means for adult Shauna in Season 3

Shauna still hasn't been able to shake Jackie's sight

Jackie has been appearing in Shauna's visions since season one. When the adult Shauna was about to jump off a bridge with Adam in an attempt to relive her youth, Jackie showed up to tell her that someone was going to get hurt. Now, in Season 3, adult Shauna is seeing Jackie again. His hallucinated reappearance could have dire consequences after the bombastic ending of Yellow Jackets season 2. The show's final season ended with Natalie's untimely death when she took a phenobarbital injection and died in Misty's arms.

The women were then told that the wilderness was pleased with their sacrifice and that they would be rewarded for it, ending the season on an ominously ambiguous note. Most bizarre elements Yellow Jackets were attributed to the psychological suffering of the characters, but there are clearly supernatural forces at play furthermore. Perhaps Jackie's reappearance isn't just a manifestation of Shauna's guilt; maybe her spirit really is there to guide Shauna. Whatever happens to Jackie, Yellow Jackets season three is without a doubt the most exciting part of the series so far.
