There are many interesting fanfictions about this. In some, the kiss might be a moment of sudden realization of their deep connection, perhaps in the middle of a dangerous situation in the maze. It could be a turning point in their relationship, where they finally admit their feelings for each other.
One possible scenario in such a fanfiction could be that after they escape the maze and find a safe haven, Thomas and Teresa start a new life together. Their baby could symbolize hope for the future in the post - maze world. It might inherit their strong will and intelligence, and grow up to be a key figure in rebuilding their society.
In many fanfictions of 'The Maze Runner' that focus on Thomas and Teresa's kiss, it often represents a significant moment of their relationship. It could be a moment of realization of their deep connection. Some fanfictions might expand on the emotions leading up to the kiss, like the build - up of trust and the unspoken feelings they've had for each other during their struggle in the maze.
A possible plot direction is that the news of the baby spreads throughout the group. Some are excited, seeing it as a sign of new beginnings. But others are skeptical. As Teresa's pregnancy progresses, they face challenges. There could be a shortage of medical supplies. Thomas has to go on dangerous missions to find what they need.

For example, he might be able to find a way to temporarily disable some of the Grievers or unlock hidden passages. Thomas could then rely on this OC's skills to lead the group to safety.
First, give your OC a unique backstory. Maybe they were an experiment before arriving in the Maze. Then, develop a distinct personality. For example, if they're really stubborn but also very loyal. Also, give them a special ability like being able to communicate with animals in the Maze, which can add a lot to the story.
