Trisha Blackhawk

Trisha Blackhawk is the main female protagonist in the short story Elsaverse: Transitions (2020-2021), which is, so far, the only Elsaverse title she appears in; she is also mentioned in the game Chasing Beth (2021), from where her last name can be inferred. Trisha is a minion working for Charles Reyes who manages to romance Jason and steals the magical book of dreams Elsa was keeping in her apartment. During that mission, it's hinted that she has some kind of unnatural ability that makes people trust her.

Personal
Trisha introduces herself in the saga as a coy but also spontaneous girl, who loves books and rock music; however, after the final revelation in Elsaverse: Transitions, it can be argued that most of those traits were just an act to make Jason fall for her: she is actually a minion who works for Charles Reyes and her mission is to steal the "Morpheus" Elsa keeps in her apartment. To achieve that, she poses as Elsa's acquaintance as well as a regular customer of Elysian Books who happens to visit the store while Elsa is away. Trisha says she's looking for a job; after a brief exchange, a charmed Jason, who has been left in charge of the business, decides to hire her on the spot. From that moment on, she tries her best to be supportive and starts to slowly flirt with him, while Jason gradually feels more and more at ease around her. Eventually, Jason falls for her and admits that his relationship with Elsa is hurting after the events depicted in Elsa's Nightmares (2019-2020); after an undetermined amount of time, they end up making love in Elsa's bedroom. In that scene, Trisha confesses to Jason that she's not the shy girl he may think; then, after a long night of sex and passion, Jason tells her all of his secrets, including the combination that opens Elsa's safe. Although she was ordered to kill him, Trisha just sedates him and then phones Charles Reyes to tell him she's opening the safe and stealing the magical book of dreams.

During that last conversation with her, Charles seems worried about Trisha being able to actually read the "Morpheus". From the Elsaverse's lore, it's known that, despite Elsa's copy being a translation, only people from the parallel universe and their descendants can actually read and understand the book to the point of casting the spells it contains; Charles' fears would point at Trisha being one of those few people in Sangrive who could do that. Trisha's origins are then confirmed in Chasing Beth, when Tanya and Tony, who have just told Joel Dresden that they came from another realm, mention her as their daughter. The story about Trisha's family and how she started to work for Charles Reyes is yet to be told. The fact that Trisha can safely elude his orders of killing Jason and call him 'Chuck' without him protesting at all shows that either they are quite familiar with each other as the Blackhawks seem to have had a long story with Morland Reyes, or that Charles is not the scary boss his father was, despite having a 'mind flayer' in his ranks, or both.

Powers
Although the exact nature and extent of Trisha's powers are yet to be confirmed, from her appearance in Elsaverse: Transitions it seems that she has the unnatural ability to make people talkative around her and trust her. Jason's thoughts about Trisha are focused on how easy is to talk to her, how he feels that he can open his heart to her and confess his secrets, and also how well clients react to her presence: after an especially hard day at work in which Trisha had to placate several annoyed customers, Jason thanks her for calming them, and she jokingly says that being a calming influence is what she does, a statement that seems to hide a big chunk of truth.
