Derek Turnbow is a recurring character introduced in the fifth and final season of Stranger Things, portrayed by 13-year-old American actor Jake Connelly. Initially introduced as a foul-mouthed playground bully who torments Holly Wheeler, Derek underwent a dramatic character arc in Volume 1, transforming from a minor antagonist into an unlikely ally for the main protagonists. As of April 2026, Derek has become a viral sensation on social media platforms like TikTok, where fans have affectionately dubbed him “Delightful Derek” due to his sharp comedic timing and surprising bravery during the Upside Down’s final incursion into Hawkins. His development from a nuisance to a “Season 5 MVP” has been praised by critics as one of the Duffer brothers’ most successful character pivots, echoing the redemption arcs of previous fan favorites like Steve Harrington. This guide explores Derek’s origins, his pivotal scenes with the Wheeler family, and the meteoric rise of newcomer Jake Connelly in the series finale.
The Introduction of a Hawkins Bully
Derek Turnbow was first introduced in the premiere episodes of Season 5 as a resident of Hawkins whose family runs the “Turnbow Land Development and Realty” company. His initial role was to serve as a grounded, human foil to the younger generation of characters.
The Turnbow Family: Derek is the youngest child of the Turnbows and the younger brother of Tina Turnbow (the popular girl who hosted the Halloween party in Season 2).
Early Antagonism: His first appearances involved mocking Holly Wheeler, reflecting the “kids being kids” dynamic that the show has maintained since its inception in 1983.
A Change in Tone: As the supernatural threats in Hawkins escalated in the 2025/2026 release cycle, Derek’s role shifted from a schoolyard nuisance to a character forced to confront the reality of the Upside Down.
Derek’s early characterization relied heavily on 1980s cinematic tropes of the “foul-mouthed brat.” However, viewers quickly noted that his bravado was a mask for the same fear felt by the rest of the town. This layered performance by Jake Connelly allowed the Duffer brothers to expand his screen time, eventually integrating him into the central conflict involving the Wheeler basement and the creeping vines of Vecna’s realm.
Derek and Holly Wheeler’s Alliance
The heart of Derek Turnbow’s narrative arc in Season 5 is his evolving relationship with Holly Wheeler. Their dynamic shifted from hostility to a genuine partnership as the “final battle” for Hawkins began.
From Bully to Bodyguard
In a pivotal Volume 1 scene, Derek witnessed a supernatural event targeting Holly near the old Turnbow Realty billboards. Instead of running, he used his “stunt” instincts (a nod to Connelly’s real-life athleticism) to help Holly escape a sensory trap set by the Mind Flayer. This moment served as the catalyst for his redemption, moving him from a background character to a tactical ally for the younger Hawkins crew.
The New “Party” Dynamic
Fans have noted that the “Holly and Derek” duo mirrors the early Season 1 chemistry of Mike and Eleven, but with a more chaotic, comedic twist. Derek brings a level of street-smart skepticism that contrasts with the seasoned, battle-weary perspective of the older teens like Nancy and Steve. This fresh energy has been cited as a primary reason for the character’s breakout success in the 2026 fan polls.
Meet the Actor: Jake Connelly
Jake Connelly’s casting in Stranger Things is a modern “Cinderella story” in Hollywood. Before landing the role of Derek, his only professional credit was a local commercial in Chicago.
The Casting Call: Jake received the life-changing call confirming his role in July 2024 while sheltering in his basement during a real-life tornado warning.
The “Mayonnaise” Secret: To keep his casting a secret before the 2025 release, Jake told his schoolmates he was filming a “documentary about mayonnaise” in Georgia.
On-Set Stunts: Known for his fearlessness, Connelly performed many of his own physical scenes, jokingly comparing his work ethic to that of Tom Cruise in promotional interviews.
Industry Reception: His performance was so impactful that the Duffer brothers reportedly expanded his episode count from four to seven during active production.
Connelly’s transition from a middle schooler in Chicago to a global star has been meteoric. His chemistry with Millie Bobby Brown and Finn Wolfhard off-camera helped him integrate into the tight-knit cast. By April 2026, he has secured several new film projects, proving that his time as Derek Turnbow was just the beginning of a significant career in the industry.
