Sadie Miller

"Sadie" is a supporting character in Steven Universe, and is a clerk at the Big Donut. She made her debut in the Pilot. She's supportive of Steven and his adventures, if only to make Lars angry.

Personality
Sadie is a clerk at the Big Donut and the co-worker of Lars. She is friends with Steven and enjoys his comebacks. Although she is friends with Lars, she doesn't like it when he makes fun of Steven. She's sweet, friendly and reserved, mature and a kinded spirit, which can sometimes leave her at disadvantage. She also values her job greatly, and is as professional as can be.

As shown in "So Many Birthdays" and "Island Adventure" she is physically capable of protecting herself and loved ones if needed, if not rather violent at times, even if she doesn't mean to.

Lars
Sadie has a crush on Lars, as confirmed in "Joking Victim". At times Lars can be a jerk to Sadie and be lazy, snobbish and rude towards her. In "Island Adventure", he kissed and cuddled with Sadie. Though the two constantly go through a love/hate relationship (Steven once called them "married" in the episode "Coach Steven") they are shown to be good friends and are almost always seen doing things together as shown in the episode "Tiger Millionaire" at the end of "Steven and the Stevens" at the Beach-a-Palooza, and watching the play together put on by Steven and Jamie in "Historical Friction".

Lars is seen to get jealous over Sadie, as in "Horror Club" he attempts to one-up Ronaldo Fryman after he is seen "flirting" with Sadie - hinting towards him starting to return Sadie's crush.

Steven
She thinks of Steven as a close friend, almost acting like a sister, even considering their age difference, she encourages his ideas and tries to help him in any way possible as seen in "Watermelon Steven" where she supports Steven's watermelon business. Even though she doesn't exactly understand his life situation, specifically related to magic and the Gems, she does her best to support him and she even knows about his mother's sacrifice, as seen in "Lion 3: Straight to Video" where she rushes to help Steven see a video of Rose.

Barbara
Barbara is Sadie's mom. It is revealed that she really cares for her daughter, Sadie, as it is seen in "Lion 3: Straight to Video" that she still packs lunches for her every day.

Ronaldo
Sadie officially meets him in "Horror Club". She treats him as a good friend, while Lars is jealous of their friendship.

Abilities

 * Fishing Skills: As of Island Adventure, Sadie has become very skilled in the art of fishing. She has fished for Steven and Lars when they got stuck on the island and was able to fight the Invisible Gem Monster with her skills to protect Lars.
 * Athletic Fitness: She is shown to be rather strong and durable for her height, being able to effortlessly hold a chair above her in So Many Birthdays,and managed to take a beating before defeating the Invisible Gem Monster in Island Adventure, despite being human.

Appearance
Sadie is short and heavyset, with curly blonde hair. She aquired a small facial scar in the episode "Island Adventure". She works at the Big Donut, so she's usually seen wearing the uniform. Her uniform consists of a periwinkle polo underneath a purple shirt, which is displaying the Big Donut logo (a half-eaten donut). She wears black leggings and pink-red shoes. Her casual outfit is a dull pink jacket, green shirt, black leggings and pink-red shoes.
