There could be a fanfic where Chloe gets pregnant by accident with Oliver in Smallville. At first, they are both shocked and a bit scared. But as time goes on, they start to see it as a new beginning. Oliver might have to face his own fears about being a father, while Chloe could be worried about how her pregnancy will affect her work or her friendships in Smallville. Eventually, they grow closer as they anticipate the arrival of their baby.
One possible plot could be that they face challenges from their families. Maybe Oliver's family has certain expectations for him and the baby, and Chloe's family is worried about her future. Another aspect could be how they balance their superhero/vigilante activities with preparing for the baby.
In certain comic arcs, Oliver Queen's fate includes his death. But it's important to note that comic storylines can be complex and sometimes characters come back or alternate timelines exist.
The plot could be that Chloe and Oliver have a secret relationship in Smallville. One day, Chloe realizes she's pregnant. They then have to decide whether to keep it a secret or tell their friends. Their friends in Smallville, like Clark, might have different reactions. Some could be supportive, while others might be skeptical about their relationship and the pregnancy. As the pregnancy progresses, Oliver and Chloe face challenges such as dealing with Chloe's health issues during pregnancy and preparing for the baby's arrival.
Maybe a story where they discover the pregnancy in an unexpected way. Like, they were on a mission together and Chloe starts feeling unwell. After some tests, they find out she's pregnant. Then it could be about how they break the news to their friends and family in Smallville. Lois might be overly excited and Clark could offer his support in a very Clark - like, selfless way.
One way is through communication. Oliver realizes his mistake and sincerely apologizes to Chloe. They sit down and talk about what led to the situation, and Chloe forgives him. Another way could be that Oliver has to go through some sort of redemption arc. He does heroic deeds to make up for what he did to Chloe, like saving her from a real danger.
One idea could be a story where Oliver Queen finds himself in Kara's universe by some sort of multiverse accident. He teams up with Kara to fight a common enemy that is causing chaos in both their worlds. Their different fighting styles, Oliver's more grounded archery and hand - to - hand combat and Kara's super - powered abilities, would make for an interesting dynamic in battles.
