Possible themes could be quite diverse. There could be a theme of self - discovery. Each character might learn more about themselves through this unique relationship. It might also have a theme of power dynamics. For example, who has more influence in the threesome relationship? Additionally, themes of love and friendship could be intertwined. They might have to figure out how their existing relationships of friendship or love are affected and transformed in this new situation. And there could be a theme of secrecy or openness, depending on how they choose to handle this relationship within their world.
I'm not sure specifically about a 'neal elizabeth and peter threesome fanfiction' on popular platforms. There are so many fanfictions out there, and it would require a lot of searching through different fanfiction websites. Some platforms might have such content if it adheres to their rules and guidelines, but it's not easy to just say for sure without actually looking.
The theme of vulnerability is also prominent. Neal being hurt makes him vulnerable, and Peter's concern is a way to protect that vulnerability. It can also explore themes of trust, as Neal has to trust Peter to take care of him when he's in a weakened state. Additionally, there might be themes of redemption, where Neal's injury makes him re - evaluate his actions and Peter is there to support his growth.
One common theme is the relationship between Neal and Peter. It could be about their friendship evolving into something deeper, like a father - son or a mentor - mentee relationship with a lot of emotional depth. Another theme is their adventures outside of the main plot of the show. For example, they might go on a secret mission together that wasn't in the original series.
Friendship is a very common theme. The unique bond between the law - abiding Peter and the con - artist Neal is often explored, like how they learn to trust each other despite their different backgrounds.
Another theme is friendship. They start as an FBI agent and a con - man, but over time, a deep friendship forms. Fanfictions often show how they support each other outside of work, like when Neal has personal problems and Peter is there for him, and vice versa.
One possible plot could be that Peter has continuously disobeyed Tony's safety instructions while working in the lab or on some high - tech projects. Tony, out of frustration and a sense of responsibility, resorts to this rather extreme form of discipline. However, this kind of plot would be quite controversial and not in line with the general positive and heroic image of their relationship in the mainstream stories. It would also be a very different take on their characters, showing a more authoritarian side of Tony.
Mystery - solving is also a common theme. Given that they are often involved in cases in the original show, fanfiction might continue this trend. They could be on the hunt for a priceless artifact or trying to track down a master criminal. Their combined skills - Neal's knowledge of the criminal underworld and Peter's FBI resources - make for exciting mystery - solving adventures.
One possible theme could be identity. How Neal, as a secretly female character, struggles to maintain his male persona while also dealing with his true self. Another theme might be relationships, like how his friendships and partnerships would change.
Love is a very common theme. Given their on - screen presence together, many fanfictions focus on different aspects of their relationship, from the initial attraction to a deep, abiding love.
The settings in neal and peter slash fanfiction can vary widely. Some might be set in the canon - like settings of the show they are from, while others might take them into alternate universes. This allows for different interpretations of their relationship. For instance, an AU where they meet in a completely different situation, like in a college campus, and their relationship develops from there.
