When Stranger Things actor David Harbour isn't busy protecting Hawkins from shadow monsters, he's making a fan's high school senior photos memorable.

Two days after Stranger Things Season 2 premiered in October 2017, Damaris Fregoso, a California high school student, took to Twitter to ask Harbour if he would grant her wish and join her in her high school senior photos. Of course, Harbour didn't jump on the request too fast, he made Fregoso do a little work before he decides.

"How many retweets for you to take my senior photos with me?" Fregoso tweeted.

David Harbour Sets Terms First Before Saying 'Yes'

Harbour immediately replied to her question and stated that she would have to get 25K retweets of her tweet. Also, if he does accept the offer, he wants to wear a school sweatshirt and hold a trombone.

Twitter users went crazy over Harbour's response. Interestingly, his costar Noah Schapp even joined in on the fun and supported the cause.

Fregoso exceeded the requirement and raked in over 29,000 retweets so, a deal is a deal. As promised, Harbour completed the request and joined Fregoso in her senior photos. 

Stranger Things Actor Shares Photos On Instagram

On Friday, the actor shared their most adorable photos on Instagram. The two both wore school sweatshirts while Harbour held pompoms and bunny ears behind Fregoso. The Critics' Choice Award winner also took photos with Fregoso's family, as well as her 5-month-old nephew.

"Voted to most likely hijack someone's senior photos 24 years later. Many thanks to @postydamaris and her kind family and @iamtommyg photography for making a dream come true and proving my high school classmates right!!" Harbour wrote.

Fregoso also took to Instagram to share the unforgettable moment with her followers.

"Senior photos 18' -bunny ear -trombone -pompoms and -smiles (twitter saw it first)" Fregoso wrote.

Is There A Season 3?

In December 2017, Stranger Things creators, the Duffer Brothers, confirmed that a third installment of the Netflix series was definitely happening. However, fans were disappointed when Harbour stated that the new season might not premiere until 2019.

In an interview with Variety, Harbour agreed that it is annoying to delay the release of a new season. However, the Duffer Brothers have plans to run the series for an at least four seasons.

While Harbour might have disappointed fans by saying that a new season probably won't premiere in 2018, fans will be halfway happy to know that he won a Critics' Choice Award. The actor received the award for Best Supporting Actor in a Drama Series.

Harbour is also nominated for two Screen Actors Guild Awards: Outstanding Performance by a Male Actor in a Drama Series and Outstanding Performance in an Ensemble Drama Series.
