One possible plot could be that on Earth X, Sara Lance and Alex Danvers are forced to team up against a common enemy. Maybe a powerful dictator has risen on Earth X and they are the only ones with the skills and courage to oppose. Sara's combat skills and time - traveling experiences combined with Alex's scientific knowledge and super strength could make for an interesting dynamic.
Another villain could be a powerful alien race that has invaded Earth X. They are much more advanced than the humans on Earth X and are trying to take over the planet. Alex and Sara would have to find a way to fight them. This could involve Alex using her knowledge of alien technology and Sara's combat skills to find a weakness in the alien invaders.
One good example could be a story where they get hurt during a fight against a powerful villain. Maybe they are outnumbered and sustain injuries while protecting each other. Another example might be a story set in an alternate universe where they are in a dangerous mission and get hurt due to unforeseen circumstances, like a trap that was set for them.
A plot where Alex and Sara are stranded on a deserted planet together. They have to rely on each other's skills to survive. Sara's combat and survival skills from her time as a pirate, and Alex's scientific knowledge could make for an exciting story of cooperation and friendship. It could also explore a possible romantic relationship between them as they grow closer during their time of isolation.
You can try searching on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. These platforms have a large collection of fan - created stories, and you might be able to find some great Alex and Sara Lance fanfics there.
They can also show the emotional toll. Maybe Sara is worried about not being able to fight as well in the future because of her injury. Alex could be feeling guilty if she thinks her mistake led to their injuries. By exploring these emotions, the writer can create a deeper impact. For instance, when they are alone in their rooms at night, thinking about what happened and how it might change things. Also, how their friends' reactions to their injuries can add to the emotional layer. If their friends are overly worried or seem distant, it can affect how Sara and Alex feel about themselves and their situation.
One possible plot could be that they discover the pregnancy unexpectedly. Maybe they were on a mission and Sara starts to feel unwell. They initially think it's something related to a recent encounter with a strange alien or time - traveling anomaly. Rip is both excited and terrified as he realizes the responsibilities that come with having a child in their dangerous line of work. Sara, on the other hand, is more practical and starts making plans for their safety and how to continue their heroic deeds while pregnant.
One possible plotline could be that they meet in a dangerous situation. For example, they could be caught in the middle of an alien invasion in their city. Alex, with her military and superhero experience, and Irma, perhaps having some unique skills of her own, team up to fight the invaders. Along the way, they start to develop feelings for each other as they rely on each other for survival.
A possible plot could be that they are forced to work together on a top - secret mission. They start off not getting along because of their different working styles. Alex is used to the more hands - on, in - the - field approach of the DEO, while Agent Vasquez has a more by - the - book, bureaucratic style from her agency. But as the mission progresses, they begin to understand and respect each other, and eventually, they develop feelings for one another.
One possible plot could be that they start off as colleagues who initially clash due to their different personalities. Alex is more reserved and duty - bound, while Cat is bold and outspoken. But as they work together on various projects in the media world related to superheroes, they gradually start to see the good in each other. A crisis, perhaps a media smear campaign against the superheroes that Alex is associated with, brings them closer. They realize they have common goals in terms of truth - telling and justice. As they fight against this, their relationship deepens and they eventually fall in love and decide to get married. It could also involve their friends and family's reactions, like Kara being super excited for Alex and Cat's mother having some reservations at first but then coming around.
A possible plot could be set in an alternate universe. Leonard and Sara are living a relatively normal life when she gets pregnant. But then, elements from their original 'universe' start to seep in. Enemies they thought they left behind start to target them because of the baby. They then have to use their skills and the help of some new friends they made in this alternate world to protect their family - to - be. It's a story of love, danger, and new beginnings all rolled into one.
