- "A girl who leaves behind a trail of glitter will never be forgotten."
- —Mariana Adams Foster
Mariana is the biological daughter of Ana Gutierrez and Gabriel Duncroft, and the adoptive daughter of Stef and Lena Adams Foster. She is also the fraternal twin sister of Jesus, as well as the adoptive sister of Callie, Brandon, and Jude Adams Foster.
Mariana is a brilliant coder who discovered her skills in high school after joining the STEAM team. After graduating high school, Mariana attended and graduated from MIT, before being hired to work at the tech up-start Speckulate as a software engineer. Mariana has since witnessed first-hand the blatant sexism and racism in her workplace and is fighting for equality.
Mariana is portrayed by actress and singer, Cierra Ramirez.
Mariana was born May 17, 1998, and is the fraternal twin sister of Jesus. She is the biological daughter of Ana Gutierrez and Gabriel Duncroft, although Gabriel was originally unaware of the twins' birth. Ana and Gabe and a consensual relationship when she was 15 and he was 18, which resulted in Ana's parents having him arrested for having sex with a minor despite her objections. Infuriated with her parents, Ana left home and began drinking and doing drugs more heavily, which was around the time she discovered that she was pregnant.
After the twins were born, Ana was still a drug addict and for this reason, Mariana and Jesus grew up in a tumultuous and unstable environment. Mariana vividly remembers a Christmas when she and Jesus were five years old and left alone at home for what felt like days while Ana was away getting drugs. Mariana described the experience as "terrifying", but, Jesus soothed her despite being scared as well. Following this incident, it became apparent that Ana couldn't care for her children due to her addiction. The siblings were placed into the foster care system soon after.
While the time they were in the foster system is unknown, Mariana was likely only in the system a year or so. Mariana lamented to Callie how she remembered frequently moving around as a foster child, and the various girls she had to room with, and sometimes being put in some "messed up" homes.
One day, Mariana and Jesus' foster parents decided that they couldn't deal with the kids anymore and dropped them off at the police station for CPS to handle. At this time, Stef Foster was a police officer and noticed the children. She approached them and learned their names before giving them each a lollipop. Mariana was quiet and didn't speak to Stef, nor did she accept the candy until Jesus handed it to her. After this, Stef and her partner Lena Adams decided to foster the twins. They brought them into their home, where they became foster siblings with Stef's biological son, Brandon. The twins were later adopted by the couple when they were 11. Mariana once said that she didn't feel true love and safety until Stef and Lena took her and Jesus in.
Mariana is very smart and girly and cares about appearances, in the least hers, very much. She's shown to be popular and is always organizing social events. Frequently, Mariana has shown strong leadership among her peers and is very proactive during a variety of situations, even organizing a protest against Mr. Timothy's firing at Anchor Beach. Not unlike the rest of her siblings, Mariana is extremely loyal and protective over her family and friends.
While she is usually kind, she can be naive when it comes to certain topics. However, she usually learns from her mistakes. Mariana also loves to gossip and speaks Spanish fluently. Despite her confident exterior, underneath it all, she can be very insecure and sometimes caves into peer pressure to be accepted. This is shown multiple times throughout the series. For example, when seeing old friend Garret had a new edgier scene and friends, she pierced her nose herself at home to fit in. When making it onto the dance team, she had overheard fellow dance teammates claiming she only made it because she's Latina. This led her to dye her hair blonde so she could fit in while distancing herself from her Latin heritage. However, she has learned not to give in to how others make her feel and to be herself.
Mariana is a young, beautiful girl with a pale complexion, dark brown eyes. She has medium length deep brown hair which she wears in a variety of styles: curly, straight, or naturally waved. She has a slim, yet toned and athletic figure. Mariana's clothing sense is very girly; she often wears bright colors, such as pinks, yellows, and blues. She is often seen wearing a mixture of floral dresses and skirts with colorful cardigans and heels, and dark jeans and jackets over bright colored shirts.
While working at Speckulate, her fashion sense was forced to change due to the misogyny at the office. She began wearing jeans, simple t-shirts, and her hair pulled back in a ponytail.
Callie catches Mariana stealing pills from Jesus. It is later revealed when Jesus discovers a large amount of cash, that Mariana was selling the pills because Ana needed money. Jesus was angered and reminded her that Ana abandoned them so she could run off with a "dumbass" and screw whoever she wanted. He was holding a picture of them and ripped it in half. Mariana tearfully tells him that Ana has come back to town. Mariana fakes a stomach ache to sneak out and meet Ana, whom she has been chatting with online. They finally meet, but it is not what Mariana was expecting. Ana takes the money and leaves suddenly. Mariana is devastated and goes home.
Mariana is blamed for reading Callie's journal. Mariana told Callie she didn't do it and knows that Callie doesn't trust her. Then, she explains to Callie the reason behind her selling Jesus' pills.
Mariana prepares for her Quinceañera and asks Callie to take Kelsey's place in her court. Callie agrees to do so. Mariana also asks Mike to do the traditional father/daughter dance with her because she is a little embarrassed about having two moms.
During the Quinceanera, Mariana finds out about Jesus and Lexi's relationship and is not happy. Mariana tells Jesus she knows about the relationship. Lexi tries to talk to Mariana in the bathroom but gets the cold shoulder. Mariana ends up dancing with Mike instead of with her moms.
Lena and her mom disagree. Lena's mom thinks that Mariana shouldn't have a party. She also says that just became Mariana thinks she is Latina doesn't mean she's Latina. Lexi insists on leaving but Jesus stops her and says it's his birthday too and that he wants at least one dance with her.
They have cake and have a family photo including Callie and Jude. They show a slideshow of Jesus and Mariana. During the slideshow, it shows some pictures of Mariana and Lexi. Mariana smiles at her. Mariana tells Lena and Stef that she is acting selfish, reflecting on what Jesus said earlier. He called her selfish because they raised her and threw her the party and she wouldn't even dance with them. Mariana apologizes to her moms, who disagree and say she is wonderful. In the end, no one saw but she did dance with them.
At breakfast, Mariana rebuffs Jesus' wanting to go to a church camp for the weekend with Lexi, and questions his religious beliefs; "Since when are you religious?" Later, Mariana meets with her birth mother, Ana, instead of seeing Garret like she told Lena. They discuss her Quinceañera and Ana even gives her a gift. Back at home, Callie and Mariana discuss Wyatt's party, and Mariana suggests that they should go. Callie reluctantly agrees before they tell the moms that they are going to Wyatt's to watch a movie. At the party, Mariana runs into Kelsey who lets slip that Jesus and Lexi had unprotected sex. Mariana, angry and upset, gets drunk and Callie decides it's time to leave. When Mariana and Callie arrive back home, Mariana makes a scene in front of the dinner party and tells Lexi's parents that Jesus and Lexi had sex. Angry, Stef and Lena put Mariana to bed.
Mariana and Jesus are fighting over the fact that Mariana told Lexi's parents that he and Lexi had sex. Stef ends the fight and tells Mariana that she brought it upon herself. Because of what Mariana did, Lexi's parents refuse to let Jesus date their daughter and have decided to send Lexi to a boarding school. Feeling guilty, Mariana helps Lexi hideout from her parents after running away. While helping Lexi, the girls talk and reconnect. After finding out from Jesus that Lexi and her parents are not legal U.S. citizens, Mariana reveals where Lexi is staying.
Mariana tells Callie that she wants Liam put away for his crimes. After class, Lexi reveals to Mariana that it's definite that she'll move to Honduras. Mariana promises to Lexi that she won't tell Jesus, but she ends up telling him anyway. Mariana removes her nose piercing for her moms to please them. Mariana dances with her family. She is asleep when Callie runs away.
Mariana and Jesus get into an argument about who gets to spend time with Lexi before she leaves for Honduras. Jesus enters Mariana's room while she and Lexi are working on their English assignment. He asks for time alone with his girlfriend, but Lexi lets him go after feeling she is letting her best friend down. She tells her that it is complicated when you are in love and that she will understand once she has a boyfriend. Mariana is left angered by this. Jude rushes into Callie and Mariana's bedroom checking her closet and her drawers only to find out that it's empty. The family has a family meeting discussing Callie. Brandon asks Mariana if she thinks Callie is back with Wyatt. She says that she doesn't think as she thinks they broke up a month ago. Brandon doesn't understand why Callie would take off. Mariana says that finally felt like she had a sister. They realize they are late for school until Stef's car won't start. At school, Mr. Timothy tells Mariana that she will need a new partner. She now finds out that Lexi is leaving for Honduras and not returning.
Marianna and Jesus confront Brandon about kissing Callie. Marianna says he is going to tear the family apart. She leaves, and Jesus tells Brandon that he agrees with Marianna. Marianna is recruited by a cute senior named Chase to audition for the school play. Marianna shows up to audition for the school play. She is greeted by Zac, who is a designer for the play. He is unimpressed with Chase, unlike Marianna. He pairs Marianna and Kelsey together to work on costumes. Marianna and Kelsey argue over working with each other. Marianna and Kelsey shop for costumes for the play, but Marianna is nervous that Kelsey will shoplift. While Marianna is trying on a dress, Kelsey shares that she thinks Chase is “hot.” When the girls leave the store, they are stopped by a security guard who wants to check their bags. Kelsey looks nervous. Marianna confronts Kelsey about the hat when Chase appears and spots the hat. He is impressed and says it defines his character. He thanks Marianna for the hat and walks off. Kelsey smiles and tells Marianna she can thank her later.
Mariana takes a liking to Chase and agrees to help him run lines after school. This angers Kelsey, so Mariana decides that neither of them should be with Chase if it means ruining their friendship. She cancels reading lines with him, but to her surprise, Kelsey offers to read lines with him instead. When Kelsey gets detention, Mariana goes to read lines with Chase, and they end up kissing. Kelsey sees this and out of anger, she tells the principal that Mariana was the one who was selling her drugs, getting Mariana suspended.
