He is my brother, but he is—He was born with something missing, I think, some piece of his heart where compassion lives.

Diego about Jaime, Lady Midnight

Jaime Rocío Rosales is a Shadowhunter from Mexico, D.F. He is the younger brother of Diego Rosales and is a distant relative of Cristina and Tomas Rosales.


Cold Peace

Jaime and Cristina had been friends since they were young. Eventually, they decided that they would someday to become parabatai.[1]

When the Cold Peace began, the Rosales families were told to surrender a powerful heirloom, among other gifts from their hadas, or faerie, connections, to the Clave, particularly as the Dearborns and the Cohort began to demand it. Instead of turning the heirloom over directly, they falsely told them that only a Rosales could make the object work.

Through all this, what Jaime wanted most in the world was to bring honor back to his family.[2] In May 2012, he and Diego were at the Rosales residence at San Miguel de Allende with Cristina. While drunk, Jaime told Diego of his intentions with Cristina: how he intended to use their shared influence on her and her mother—with Diego as her future husband and him as her parabatai—to gain control over the D.F. Institute, believing that the wrong branch of the Rosales family was in power. He went as far as telling Diego that he was stuck with the harder position as being parabatai with Cristina would mean they are stuck forever.

Since Jaime planned to go to Idris, Diego meant to warn Cristina about him but never had the chance as she had already overheard Jaime's rants. Heartbroken, she left and moved to Los Angeles. Despite his drunken ramblings, he, according to Diego, still panicked when Cristina left. Also according to Diego, he only said those things because he had been drunk.[1]

With Cristina and their strongest connection to the D.F. Institute gone, they became more pressured to give or hide their heirloom. To delay the Dearborns' demands for the heirloom, Diego tied himself to the Cohort in an arranged marriage to Zara Dearborn, while Jaime took the heirloom and went into hiding.[2]


Jaime, who had been missing and unreachable for months, snuck into the London Institute after hearing Cristina was taking refuge there. He was discovered by Dru Blackthorn, who immediately developed a crush on him. He told her that he was there to see Cristina, but she couldn't know he was there yet. Jaime began hiding in Dru's room. His trust and reliance on Dru, as well as his charm, made her feel special.

Eventually, Jaime spoke to Cristina. He delivered a letter to her from Diego and explained to her his situation and tried to explain as much as he could why he'd said the words that hurt Cristina. He also told her to send him a fire-message if a fight against the Cohort came because he wanted to participate. Jaime refused to tell her where he was headed next and asked her not to tell anyone he was ever there.

After he met with Cristina, Dru curiously looked at the contents of his bag and accidentally touched the heirloom and she was transported to a room in the Unseelie Lands. During that short time, Jaime gathered his things and left her room. He left before the next morning, but not before leaving a farewell gift for Dru in the form of a gold Rosales hunting dagger with a thank you note.[2]

Saving Diego

Cristina reached out to Jaime not long after, asking for his help. When he arrived at the Los Angeles Institute, he went to see Dru on the beach first before going inside. Cristina explained that they needed the Eternidad he had been protecting in order to rescue Julian Blackthorn and Emma Carstairs. He allowed her to take it and after they left he prepared to leave the Institute. While Dru and Helen tried to convince him to stay for dinner, a fire-message arrived announcing The Registry and Diego's arrest. Jaime left quickly to try to break his brother out of jail.

Jaime was captured and contained in Idris where he was severely beaten up by Cohort members. His brother, Diego, was also contained for housing the Unseelie prince, Kieran. Jaime's wound on the arm became infected and his condition worsened over time. Diego begged the Cohort to give him medicine or a stele to draw a healing rune, to no avail. Eventually, Anush Joshi, who was in charge of bringing them food as punishment for abandoning his teammates on a mission, realized the error of the Cohort's ways and secretly tucked a stele and gave it to Diego. Jaime was soon healed and then they escaped.

During The Cohort's parley, Jaime and the others joined Livia's Watch to fight against the Cohort. Jaime later helped Dru get onto the Imperishable Fields to meet with her family and helped them get to Julian and Emma, who had become True Nephilim. On the way he spotted his brother's limp body being dragged by a redcap, to which he quickly dispatched and saved and healed his brother.

A few weeks later he attended a party on the beach in Los Angeles that later turned into Magnus Bane and Alec Lightwood's wedding. There he approached Dru and tried to make polite conversation, asking if she would be attending the new Academy. When Dru asked if she'd see him again, he confessed it was not likely as he needed to return home and fix things with his father and the rest of his family.[3]

Personality and traits

Jaime is warlike and fierce, more so than his brother, Diego, for which he sacrifices a bit of his grace. He was also troublesome, often getting his brother in trouble for his actions.[1] He has a restless and mischievous spirit, playful where Diego is serious. He plays devil's advocate in arguments. Jaime was also secretive, often disappearing for long periods of time without saying where he was going.[4]

He has a strong accent—stronger than that of Cristina's or Diego's.

Physical description

Jaime is tall and rangy, his months on the run making him even thinner. He has black hair, typically untidy, brown skin, brown eyes, and long, black lashes. Aside from his Marks, Jaime is also covered in tattoos. He has sharp features, a slightly big nose, and a wide mouth. Despite apparently not being as handsome as his "perfect" brother at first glance, it is highly subjective, and his charm may easily change one's opinion about his looks in comparison to Diego.
