Caution: The following content includes spoilers from the season 2 finale of Cruel Summer.

In Cruel Summer's season 2 finale, Freeform intriguingly incorporated a significant Easter egg, bridging the storyline with season 1.

In the conclusion of the sophomore season, aired on Monday, July 31, Megan (Sadie Stanley) retrieves her keys from atop a book titled "Out of the Basement: The Kate Wallis Story."

Introduced in season 1, Kate Wallis (Olivia Holt) was the focus of the show due to her kidnapping and subsequent rescue. Jeanette Turner (Chiara Aurelia), a fellow student, was accused of knowing about Kate's whereabouts but concealing the information. The first season's final scene revealed that Jeanette was aware that Kate was held captive in the basement of their vice principal, Martin Harris (Blake Lee).

Freeform's confirmation that Cruel Summer would be an anthology series for its second season brought about an even greater shakeup for viewers. The return of the hit series in June introduced new episodes that delved into the constantly changing dynamics of the friendship between Megan and Isabella (played by Lexi Underwood). The enigmatic love triangle between them and Luke Chambers (portrayed by Griffin Gluck), culminating in his tragic demise, has been the focal point of this gripping mystery.

Ahead of the season 2 premiere, executive producer Michelle Purple intriguingly hinted at a shared universe among the characters.

"We gave significant thought to the fact that viewers had a genuine fondness for the cast in season 1 and were emotionally invested in them," she stated in June during an interview with TVLine. "We even went as far as creating a dedicated space to discuss how we could effectively continue the stories of both these girls, or perhaps just one of them."

Purple also mentioned, "We are exploring the same universe, as it takes place a few years later. There is a connection to season 1, but we won't be revealing it! That discovery is in your hands!"

In the same month, Stanley and Underwood, both in their early twenties, shared insights into their conversations with the season 1 cast.

"It was absolutely amazing to have the season 1 team, who truly understood the formula and structure of the show. It can be challenging to tell a story while also portraying three different versions of your character or handling different timelines," Underwood exclusively revealed to We. "Having their guidance really alleviated the pressure of trying to surpass anything or meet certain expectations. Whenever we interact with the season 1 cast, they are incredibly supportive and loving towards us."

Stanley commended Aurelia, 20, and Holt, 25, for the valuable advice they provided after their roles in Cruel Summer.

"Both Chiara and Olivia have shown incredible support and reached out to both of us," Stanley expressed to Us. "I've had the pleasure of meeting Chiara a few times, and she's truly wonderful. Olivia also visited the set while we were filming in Vancouver, and she's absolutely fantastic."
