–Suzie, "The Battle of Starcourt"
Suzie attended summer camp at Camp Know Where, where she met Dustin Henderson. She first met Dustin when Dustin alighted off the bus at Camp and stood up to two bullies. She was one of the bystanders who applauded Dustin's verbal defense against the two bullies. Suzie gradually developed an attraction to Dustin, awed by his actions in standing up against the bullies repeatedly as well as his stories about life at Hawkins.
Suzie asked advice from a counselor named Dawn who advised her to use science as a topic of interest for the two of them to talk about. Suzie then approached Dustin as he was busy writing his own Dungeons and Dragons game session. Suzie quickly mistook Dustin's words as a rebuke, causing her to run away without even introducing her name. The next day Suzie attempted to talk to Dawn again to get advice, but discovered that the counselor had apparently left. Later she started doing math near Dustin on the same field, which caused Dustin to notice her. When she attempted to approach Dustin later as he was composing his game session, Dustin called out in anger, not knowing it was Suzie. Suzie then fled once more, filling Dustin with regret.
Dustin then tracked down Suzie and expressed his sorrow at the misunderstanding, the two finally getting a chance to properly introduce themselves. The two then overheard a conversation between the camp counselors where they were discussing a possible killer on the Camp premises. Dustin then resolved to find out who the killers were and why, although Suzie put up a light protest, asking if the shouldn't just let the counselors resolve the situation on their own. She also reminded him that they were kids, thus limiting their options. But Dustin pointed out that them being kids was advantageous, as they would not be targets to the possible killer. Suzie then felt empowered by his words, agreeing wholeheartedly and racing past Dustin in determination.
The two eventually entered a relationship. While the couple had to part ways when camp ended, they agreed to continue contacting one another. Dustin returned to Hawkins, where he attempted to reach her through his ham radio and introduce her to his friends, who were shocked and suspicious of her existence and her almost perfect nature. However, she did not pick up for the rest of the day, causing the Party to conclude she did not exist. However, Dustin had discovered a Russian's presence on the radio channel and brought it to his friend Steve, Robin, and eventually, Erica's attention. Throughout the investigation of the Russians, Dustin constantly compared Steve's romantic feelings for Robin towards Dustin and Suzie's, much to Steve's annoyance.
On July 4, Dustin contacted Suzie all the way to Utah in need of Planck's Constant. While reading, she is shocked to hear from him and finally says that she copies. She asks "Dusty-Bun" where he's been, and Dustin explains that he has been busy saving the world from Russians and monsters. She giggles and says of course he has. Erica whispers for Dustin to get the number, causing Suzie to ask who else is there. Dustin nervously lies and says it was simply interference and to change frequency. Suzie complies and changes frequency. He asks her if she knows Plancks's Constant, to which she confirms. Dustin asks what it is, Suzie says that she hasn't heard from him in a week and now he wants a mathematical equation so he can save the world. Dustin promises that he'll make it up to her as soon as possible, but Suzie says he can make it up to her now. Confused, Dustin asks what is she talking about. Suzie simply says that she "wants to hear it". Dustin, embarrassed, says not now, but Suzie demands him to do it or she'll sign off. Reluctantly, Dustin and Suzie begin singing a duet of the theme song for The Neverending Story, much to the confusion and annoyance of the group. After finishing, she says Planck's Constant, and Jim and Joyce unlock the code for the keys. Dustin says that she just saved the world, and Suzie says that she misses him "multiplied by all the stars in the galaxy. As the two proclaim their love for one another, Erica turns off the radio, leaving Suzie confused.
Three months later, Lucas and Max tease Dustin by mockingly singing the theme song, angering Dustin. Max asks if they can hear Dustin's rendition, but Dustin objects, saying that it's for Suzie's ears and Suzie's ears alone, showing she and Dustin are still in contact with one another.
Suzie is set to appear in the comic series, set nearly a month prior to the third season. It focuses on her time at Camp Know Where, where she meets Dustin and gets roped into an adventure of her own.
Like Dustin, Suzie is interested in science and comics. Due to her religious family and appearance, it's likely Suzie is sheltered and quiet, which leads to her nerdy nature. When Dustin calls Suzie asking if she knows the Planck constant, she jokingly remarks, "Do you know the Earth orbits the sun?", reciting the complicated number by heart, showing her to be an intelligent and studious girl. It is shown that she can operate a ham radio, as that is her main mode of communication with Dustin. She is also quite sentimental and romantic, being particularly joyous to hear from Dustin and seems to particularly enjoy singing with him. There's also some hints of jealousy to Suzie, as when she hears Erica murmur to Dustin to get the number already, Suzie suspiciously asks who that was, but Dustin lies by saying it was someone overlapping the frequency.
Suzie is Dustin Henderson's first girlfriend, having met at Camp Know Where during June of 1985. They share a love of comics and science. Unlike other girls Dustin has interacted with, Suzie does not care about Dustin's cleidocranial dysplasia, saying that "kissing is better without teeth". Dustin's view of Suzie is slightly warped (but in a good way), viewing her as "hotter than Phoebe Cates" and describing her as the perfect woman. When the two departed once camp was over, Dustin bestowed her his old hat, which she kept by her bedside table. After returning to Hawkins, Dustin attempts to reconnect with her through his radio and introduce her to his skeptical friends, but she does not respond. After Dustin contacts her in need of Planck's Constant, Suzie is proved to exist and is extremely enamored with him. The two refer to each other by pet names ("Suzie Poo" and "Dusty Bun") and they perform the theme song to The Neverending Story. She is mentioned by Dustin three months later that his rendition of The Neverending Story is for Suzie's ears only, showing they still talk to each other.
Although the group of friends has yet to meet Suzie physically, she is mentioned frequently by Dustin throughout the third season. Mike, Will, El, Max, and Lucas were shocked and skeptical of her existence and perfect nature. After Dustin fails to get in contact with her, the group concludes she is probably fabricated. The next day, he tells Steve, who believes the same thing. Dustin then compares his and Suzie's relationship with Steve's romantic feelings for Robin, much to his annoyance. On the night of July 4, while Robin, Steve, Dustin, and Erica ride towards Cerebro, Robin says to Dustin that Suzie must be worth lugging the radio out in the middle of nowhere just to speak to her, but Erica and Steve remain skeptical of her existence. It is not until Dustin and Suzie sing their song that the group is convinced of her existence (but are confused by their duet). Three months later, Max and Lucas tease Dustin of his duet by singing it while they help the Byers move, much to Dustin's anger. Between July and October of 1985, it's currently unknown whether they have been introduced to her by Dustin, but it can be assumed he most likely did not due to their knowledge of their duet.
