Jason

Jason is the player's character (PC) in Dreaming with Elsa (2015), the first game ever set in the Elsaverse. He also appears in several other titles, either as a protagonist of some short stories or as a side character. Jason is currently working as a manager of Elsa's bookstore; during that tenure, he has cheated on her with Trisha.

Personal
In order to allow players to self-insert themselves more easily, when Jason is first introduced as the PC in Dreaming with Elsa he is basically a blank slate: throughout the game, the only background information provided about him is that he lives alone and works as a delivery man for a publishing company, despite having an university degree (in one of his dates with Elsa, the player can choose his major, but that detail is completely irrelevant on the Elsaverse canon). There's no clue about what he likes or dislikes, about his family or past relationships, and his only known friend is his colleague, Conner, who doesn't have any problem to deceive him following Chloe's orders. This lack of depth besides being Elsa's boyfriend is carried over next titles, where little else is unveiled about him.

Although he is always a supportive and respectful man, in DwE players can choose whether Jason is a sweet and romantic guy or a more daring and sexual one; however, once that game is over, Jason's canon personality is clearly the former. This makes him the perfect match for Elsa, and the man she needs by her side while she evolves from a shy and insecure girl to a powerful Dream Master. During the short stories that follows Dreaming with Elsa, he is depicted as a quiet, calm, and hard worker man, a man who is deeply in love Elsa but is also a bit insecure about himself. He is mature enough to not be freaked out by Elsa's powers; quite the opposite, he's amazed by them and doesn't feel any jealously of her being more and more powerful. However, as she keeps growing and becoming a more and more confident girl, he starts to second guessing himself, as she is not the girl she first met anymore.

Things got more complicated for him after Morland's defeat. In Elsa's Nightmares (2019-2020) Jason becomes the victim of Elsa's inner self, who abuses him, suffocating him and then breaking him one of his fingers, in order to make Elsa stop using her powers just for sex. Although she was not consciously hurting Jason, the fact is that she indeed hurt him, and their relationship suffered from it. In Elsaverse: Transitions (2020-2021) it becomes apparent that the couple weren't able to properly clear things up, so Elsa's trip to Switzerland to help Miranda becomes a convenient opportunity to let time heal the wounds. Being left as Elysian Books manager during Elsa's absence, Jason decides to hire an extremely friendly stranger called Trisha as a shop assistant. It's hinted that she has a power to make people trust her and being talkative to her, and Jason falls entirely for it, using her as a couple therapist to verbalize his doubts about this new Elsa. Finally, she ends up seducing Jason and having sex with him on Elsa's bed; Trisha then is unveiled as a new villain, as she sedates Jason (although her boss asked her to kill him) and steals the "Morpheus".
