Jonathan Joestar/Personality and Relationships

Relationships

Family

• George Joestar I: In his youth, Jonathan's father was very strict on him, correcting his lack of table manners and berating his studies, while ignoring the harm that Dio was bringing on his son. This was perhaps made worse by the fact that Jonathan's mother had died some years ago, hardening George and causing him to be harsher on his son. Regardless, Jonathan still loves his father greatly, angrily beating up Dio, whom he had been friends with for the past seven years, for poisoning his father. When Dio throws a knife at Jonathan, George sacrifices himself to block the knife and comments that "it's not so bad to die in your son's arms".
• Mary Joestar: Though Jonathan's interactions with his mother are never seen, he is shown to love her greatly, looking at her picture wistfully and crying right after Dio ruins his life with his arrival.
• Danny Joestar: Jonathan and Danny have forged a strong bond since Danny saved Jonathan from drowning in the river. Jonathan is shown to be very angry when Danny was kicked by Dio and had sobbed uncontrollaby when the household had buried Danny. Danny still shows up in his master's memories, when Jonathan remembers having fought with Danny over a bone.
• Dio Brando: In their childhood, Dio and Jonathan do not get along well due to Dio's antagonism towards Jonathan and his ability to both outshine him and ruin his relationships greatly. Years later at Hugh Hudson Academy, Jonathan is shown to have become friendly with Dio, though Jonathan still suspects that something is suspicious about Dio's behavior and Dio had been plotting to take over the Joestar household. Their antagonism reaches a peak when Dio poisons, and later kills, Jonathan's father and transforms into a vampire. Regardless, both maintain some degree of respect towards one another, as shown when Jonathan suicidally attempts to pin Dio on a pointed statue as the Joestar mansion burned down and Dio acknowledging Jonathan when he arrives on board the ship to America to take Jonathan's lower body. Their relationship sparks a legacy that continues well into the future parts of the series.
• Erina Pendleton: Jonathan's love interest and eventually his wife first hands him a handkerchief shortly after he is beaten down by bullies. Jonathan professes his love for her afterwards, which she is shown to accept at least in part, until Dio enters and steals her first kiss in order to upset the two. Erina does return after the Joestar mansion burns down, however, and nurses Jonathan back to health, igniting the relationship between the two once more. The two are married after Jonathan manages to defeat Dio with his ripple, and their relationship continues well into Erina's old age, where her memories of Jonathan prevent her from entering a relationship with Robert Speedwagon.
