The 'redemption arc' for Wesker is also a common trope. In some fanfictions, Wesker might have a change of heart due to his interactions with Chris. This could lead to him trying to make amends for his past actions. And of course, the 'forced proximity' trope, where they are put in situations where they have to be close to each other, like being trapped in a facility together. This can accelerate the development of their relationship, be it friendly or romantic.
One popular trope is the 'enemies - to - lovers' scenario. Given their antagonistic relationship in the main Resident Evil storyline, it's not uncommon for fanfiction to explore the idea of them gradually developing feelings for each other. Another trope is the 'power imbalance' where Wesker's superior strength and abilities create a dynamic where Chris has to constantly struggle to keep up.
The fanfiction might also focus on their shared history. They've both been through a lot in the Resident Evil world. There could be scenarios where they remember past encounters and how those memories shape their current interactions. For example, perhaps a past mission where they had a moment of mutual respect that is now overshadowed by their current enmity. Writers can use this to build a more in - depth and nuanced relationship in the fanfiction.
One popular trope is the 'forbidden love' trope. Since Chris is often in a position of power as the host in Total Drama, a relationship with a reader - insert character might be seen as inappropriate or against the rules. Another common trope is the 'fish out of water' scenario. The reader could be from a completely different background than the crazy world of Total Drama, and Chris helps or hinders their adjustment. There's also the 'redemption arc' trope for Chris. The reader might be the catalyst for him to change his ways and become a better person.
The theme of friendship evolving into something more is also quite popular. It starts with their strong friendship as comrades in the fight against bio - threats, and then it gradually develops into a deeper, more romantic or at least more intimate relationship as the story progresses.
Another theme is the unspoken or developing romance. Since their relationship in the games has undertones of a deeper connection, fanfictions often build on that. They might write about the moments when they first realize their feelings for each other, like a shared look during a tense battle or a quiet conversation after a difficult mission.
Wesker in Resident Evil 5 was a complicated character. He had both an evil side and a human side. In the movie, Wesker was portrayed as a scientist who controlled the zombie virus. He was committed to spreading the zombie virus around the world to achieve his goal. However, he also showed some human side. For example, after he was defeated by Alice, he showed pain and sadness and tried to find a solution instead of simply giving up. Therefore, we can't simply describe Wesker as a good or bad person, but a complex character with a human side and an evil side.
One great fanfic is 'Together Against Evil' which focuses on their teamwork and the underlying romantic tension. It has well - written action scenes that are true to the Resident Evil universe.
I'm not entirely sure which specific 'chris x wesker infected fanfic' you are referring to. However, in general, such fanfics often explore the relationship between the characters Chris and Wesker in the context of some sort of infection.
