DISCLAIMER: In canon, Henry is only a prisoner of Javier for a year and only two days in the early 2000's. I've adjusted this for character angst, Henry was a prisoner of Javier's for 30 years in the 15th century and for a month in the 2000's.
𝐉𝐀𝐕𝐈𝐄𝐑 𝐌𝐄𝐍𝐃𝐎𝐙𝐀: Henry encountered Javier Mendoza shortly after he and his maker, Christina, went their separate ways. Henry allowed his self-control to slip, and against his better judgement, began acting recklessly and impulsively. This drew the attention of Javier who was a devout member of the Spanish Inquisition stationed in France. Henry had only been a vampire for a year and a half, his presumed death as the bastard son of Henry VIII almost seven years previous.
Unlike many of Javier's colleagues and fellow religious consorts, he believed in the occult, in witchcraft and the supernatural. He led a small rogue band in his tribunal who specifically targeted the inhuman. Henry was eventually captured, imprisoned, and tortured by Javier and his sect. For thirty years, Henry refused and defied him, eliciting an obsession in Javier as he conjured more and more creative and disturbing techniques to force a confession from Henry. Javier grew more and more disturbed as the years went on and Henry continued to resist him.
During their time together, Javier and Henry would engage in intellectual arguments, debates, conversations, and discussions on spirituality, religion, war, and belief in-between intervals of Henry's torture and punishments. They skirted around the edges of each other, and Henry learned every dark, twisted, and unholy thought, belief, and feeling that Javier had ever had. He became Javier's confidant and confessor, free from judgement, Javier could unburden his soul in relative safety.
Henry would eventually escape Javier's clutches after befriending Maria Mendoza, Javier's dutiful wife. Throughout Henry's time as Javier's prisoner, Javier trusted only his wife to be in Henry's present without falling to Henry's "evil". Like Javier, Henry would engage in deep conversations and discussions with Maria whenever Javier was away and found her to be the opposite of his captor. She was kind, gentle, faithful, and strong willed. She believed in compassion and forgiveness, and it was these things that Henry fell for and what he used to convince Maria to free him. When she freed him, Maria asked for Henry to turn her, believing that she could save Javier's soul by demonstrating to him that she was still the same woman he loved and cherished after her transition.
Despite his reservations, Henry agreed to help her, promising to return the next night. However, Harry arrived seconds too late. Maria awoke to see the face of her love, and Javier plunged a stake into her heart, killing her instantly.
Henry snapped. He lashed out, impaling Javier and going on a killing spree through the church where Javier had imprisoned him for three decades. He spent the next fifty years hunting down and killing all members of Javier's tribunal. It is one of the darkest centuries of Henry's life.
For centuries, Henry believed Javier was dead until the priest returned in the early 2000's. Javier had discovered a way to prolong his life using vampire blood and mystical herbs and concoctions. Javier manipulated Mike Celluci, prying on his fear and jealousy, to help Javier weaken and capture Henry for the second time. Cut off from Mike and Vicki, Henry was once again at the mercy of Javier Mendoza.
As his captive, Henry discovered that Javier had been tracking Henry by following the lives of those he had turned. Capturing, torturing, and forcing them to confess to being abominations, to name their sire, and beg for salvation. Javier recorded each confession, as well as their execution by sunlight.
Henry spent a month as Javier's prisoner being tortured by an enchanted object that rapidly caused desiccation, starvation, and extreme pain. By the time Vicki and Mike found him, Henry was half-crazed with hunger. Mike intercepted Henry before he could feed on Vicki, and Vicki in turn managed to stop Henry from draining Mike dry. He turned his hunger and rage on Javier, hunting him down and killing him once and for all.
