It would likely become more intense. Clark would be more protective of Lana, constantly worried about her and the baby's safety. Lana, on the other hand, might rely on Clark more for emotional and physical support.
One idea could be that Clark discovers Lana is pregnant and he has to deal with his dual identity as he tries to protect her and their unborn child from the various threats in their world. Maybe he builds a special safe haven using his powers.
A great Smallville Clark and Lana lemon fanfiction might be one where their relationship is put to the test by an outside force. For example, a powerful alien entity arrives in Smallville and tries to drive a wedge between them. This could lead to some really intense and emotional scenes between Clark and Lana. Another type of fanfiction could be a coming - of - age story for their relationship. It could start from when they were just kids with a crush on each other and follow their journey as they grow older and face different obstacles. And then there are fanfictions that focus on their shared dreams and how they try to achieve them together, like Lana's dreams for her career and Clark's dreams of using his powers for good, all while being in a relationship.
In fanfictions, they often develop their relationship through shared secrets. Clark may gradually share more about his powers and his alien origin with Lana, which deepens their bond. For example, he might show her a small part of his powers at first and then as she accepts it, he reveals more.
One idea could be that Clark and Lana start a business together in Smallville. They have to overcome financial difficulties and competition from other local businesses. This would test their relationship as they deal with stress and make decisions together.
It could be Clark. Given their on - again - off - again relationship in the show, it would make sense for Clark to be the father. Their relationship has always been complex and a pregnancy would add a whole new layer of drama to it.
One popular storyline could be Lana's journey during her pregnancy. Maybe she discovers she's pregnant while on a Pokemon adventure and has to balance taking care of herself and her unborn child with her Pokemon training. For example, she might have to take a break from some of the more dangerous battles or explorations. Another idea could be how her Pokemon react to her pregnancy. Some Pokemon might be very protective, like her water - type Pokemon creating a safe perimeter around her. And there could also be a story about Lana preparing for the arrival of her baby, such as making a special nursery with the help of her Pokemon friends, using their unique abilities to decorate or gather supplies.
Obviously Lana herself is the central character. Her Pokemon partners are very likely to be involved. For example, Popplio might be constantly by her side, providing emotional support. Ash and his Pikachu could also be part of the story. Ash, being a good friend, would probably offer his help and advice. Misty might also be there, sharing her own experiences or just being a good friend to Lana during this time. Brock could be involved too, perhaps using his knowledge of Pokemon and nature to ensure Lana has a healthy pregnancy. And other trainers from the Pokemon world who are friends with Lana might make appearances to show their support and be part of the story.
Yes, there are many Smallville fanfictions that focus on Clark and Lana having a deep emotional bond rather than just a romantic relationship. Some explore their friendship growing from their shared experiences in Smallville, like dealing with the strange happenings in the town together and supporting each other through family and personal issues.
