Hannah Webster

Hannah Webster was originally the name of a human who was the assistant of the successful Buckland Auction House owner Rex Buckland until the two were murdered by two warlocks who assumed their identities to establish a foothold in the mortal world to the benefit of the Underworld.

The warlock Hannah was able to ignite fires with her breath, as well as shapeshift. Rex and Hannah had been dispatched by the Source to acquire the powers of the Charmed Ones. Hannah, along with Rex, began to watch the oldest of the Charmed Ones, Prue Halliwell, once Prue has been hired at the auction house. Hannah and Rex are in a relationship and she gets extremely jealous whenever any other women even talk to him. Because of this she spent most of her time trying to find ways to annoy Prue, such as tricking her into doing useless work at the auction house and stealing her sandwich.

Meeting Prue Halliwell
After Prue quit her job at the American Museum of National History, due to a brutal breakup with her boss, she applies for a job at Buckland. Prue feels she is not right for the job, but reluctantly goes anyway. Rex agrees to an interview with her, but despite her running late she bumped into him while in the elevator, where they have the interview shortly afterwards. After succeeding, Prue has a second interview where she meets Hannah for the first time. While there, the warlock couple test Prue's abilities regarding antiques and artifacts. After Prue describes the statue the little dancer, Hannah "accidentally" knocks over a white paint can, causing Prue to flinch and use her newly aquired power to avoid being hit. The paint gets all over Hannah's shoes, something that greatly angers her. They notice her power usage, with Hannah swiftly believing that Prue is a witch.

The Spencer-Michaels Wedding
When Elliot Spencer and Allison Michaels' wedding came around, it was revealed that the demon Hecate had made a deal with Elliot's mother so that Hecate could give birth to an heir. To help facilitate this process, Rex was given a female fertility icon that supposedly helps a woman conceive, as long as it is near them. With Piper catering the wedding, their intention was to get Phoebe and Prue involved in the same event so the warlocks can make their move. However Hannah's incompetence resulted in Prue cataloguing the fertility icon. Later, Prue receives a male version of the same icon, when Rex reveals the female icon was a gift for the Spencer-Michaels wedding. Prue remarks that her sisters were organising the catering for the event as well. Rex tells Prue to catalogue the icon anyway. Later that night, the sisters spy on Hecate's hes night when Prue notices the icon. One of Hecate's bridesmaids, Kirsten, states that "they understand how important it is for you to get pregnant right away."

Trying to avoid the Truth Spell
Tanya Parker is delivering sandwiches to Buckland's employees when she reaches Prue's office. Tanya saves the final turkey sandwich with no mayo for Prue when Hannah walks in and takes it. Not knowing that Prue cast a Truth Spell, Prue asks her why she took it if she didn't like it. Hannah responds that she doesn't like it, she just doesn't want Prue having it either. This angers Prue who asks why Hannah is such as bitch to her, to which Hannah replies that it is her mission to destroy her (literally), thus almost revealing herself as a warlock to Prue when Rex walks in. He laughs it off and takes Hannah outside to tell her off. He takes a cigar out - and Hannah blows on it, causing to light up and smoke. This is the first definitively supernatural sign that they are after the sisters and their powers. ("The Truth Is Out There... and It Hurts")

Matthew Tate
In another attempt to kill the sisters and obtain their powers, Rex comes across a cursed locket and gives it to Prue. She opens it, which results in the escape of a warlock known as Matthew Tate, Melinda Warren's former lover. Knowing that only a descendant of her can open the locket, he tries to kill Prue, but only ends up copying her powers and escaping, with Rex listening in from the outside. Rex and Hannah are interviewed by the police regarding the ambush before celebrating their success. Rex and Hannah later catch Matthew after he killed a shopkeeper with the surname Halliwell and offer to to help him obtain the sisters' powers. However they have an ulterior motive - they want the powers themselves and intend to banish Matthew back into the locket as well. The task fails after Matther is returned to the locket but knowing that the sisters are the Charmed Ones, Rex admits that they should've gone after them directly after trying to do so secretly. ("The Witch is Back")

The Beginning
Rex and Hannah waited until they saw an opportunity to steal the Charmed Ones' powers. Rex was able to utilise his new astral projection power to set certain events into motion. He first starts by hypnotising Prue into taking a tiara under the pretense of her date book and stow it in a drawer in her room. After he comes back, he proudly states that the plan is underway. Hannah is confused about the new power, but comes to understand after astral Rex successfully convinces her to take her dress off without her realising. After Rex gives Hannah's ticket to go and see the Verve to Phoebe, she becomes upset but Rex consols her, telling her that upsetting Prue would give her a motive to steal the tiara in the minds of the police. In reality, Rex had no interest whatsoever in Phoebe and is in love with Hannah. Manipulating her was part of the plan. ("Wicca Envy")

Murdering Jaime
Hannah hides one of the security tapes - the one with Prue stealing the tiara in order to blackmail Prue and the sisters to give up their powers. After Jaime, the security guard, confesses to Prue that he believes her innocence and she returns to her office (and he to his patrolling), he is killed by a blow to the head with an artefact that Hannah was holding, and the artefact that Prue was to pick up upon the discovery of his body due to Rex messing with her mind (to warn her of a warlock attack and to grab an artefact - the same artefact Hannah used to kill Jaime.). She also dumps the incriminating tape by his side, thus prompting Andy and Darryl to arrest Prue upon their arrival. This was after Prue checked the identities of Hannah and Rex on the Bucklands website, and failing to gather any information on them as a result.

Hannah is Found Out to be a Warlock
Phoebe seeks Rex's help with their predicament, but when she and Piper turn up at his "apartment" it is blank - except for her lipstick. Phoebe and Piper realise that Rex is a warlock - and if Prue is believed to be correct, so is Hannah.

Hannah turns into a panther
When Rex announces that the sisters have placed their powers within the lantern object. Hannah is pleased at their success. She then drops to the ground and crawls to Rex in a sexual manner before shapeshifting into a black panther in preparation of killing the sisters.

Hannah and Rex's Death
While Hannah prepares to attack the Charmed Ones, their powers escape from the lantern Rex was holding (thanks to Leo who "healed" the Book of Shadows in the manor). Rex demands Hannah to kill them; as she jumps to scratch them to death, Piper put both hands up and freezes her in midair as well as Rex. Prue then uses her telekinesis to move Rex just in front of Hannah. The scene unfreezes; Hannah lands on Rex and kills him with her fangs. She morphs back into her human form, only to be horrified by what she's done. She gets up and yells at the Charmed Ones. Hannah and Rex's body are then surrounded by flames; Hannah desperately screams, telling it was not her fault. Rex and Hannah are finally vanquished.
