Their relationship could develop slowly. At first, Shego might be in denial about her feelings. She could try to push Ron away, but Ron's kind and somewhat bumbling nature in handling his pregnancy situation keeps drawing her back. Eventually, she accepts her feelings and they start to build a bond based on mutual understanding and support.
One possible plot could be that Shego, who has always been a villain, starts to see Ron in a new light. Maybe she first gets close to him out of curiosity because of his relationship with Kim. As she spends more time with Ron, she realizes his kind heart. And when she discovers he's going to be a father, she's drawn to his new sense of responsibility and falls in love.
One common theme is the 'opposites attract' concept. Shego is a villain - ish character while Ron is more of a hero - sidekick. Their different personalities and moral alignments make for an interesting dynamic when love enters the picture.
Their relationship would likely become more complex. Ron, who is usually carefree, would have to become more responsible. He would need to support Shego both emotionally and physically during her pregnancy. Shego, on the other hand, would have to trust Ron more. She might be used to being self - reliant, but now she has to rely on Ron for things like getting things for her when she can't move easily. They would also have to communicate more about their future and the future of their child.
Ron might be shocked at first. But then, being the good - hearted person he is, he would probably offer his help. Bonnie, on the other hand, could be a bit more hesitant. She might be worried about how this would affect her marriage to Ron. However, as time goes on, she would also come around and be supportive.
Well, a plot twist could be that the pregnancy is not as straightforward as it seems. Maybe there's some sort of magic or science - fiction element involved. For instance, the baby could have some superpowers that start to manifest even before it's born. This could attract the attention of various factions, both good and bad. Ron and Shego would then have to navigate through these new threats while also dealing with the normal pregnancy issues. Or perhaps, the pregnancy was caused by an accidental encounter with a strange artifact, and now they have to figure out how to ensure the baby's health while also finding a way to reverse the effects of the artifact if necessary.
Perhaps in this fanfiction, Ron and Bonnie are happily married but then Shego shows up pregnant. It could turn out that the baby has some sort of special power or connection to their world. Ron, with his experience in dealing with strange situations, might take it upon himself to protect Shego during her pregnancy. Bonnie could be initially jealous or suspicious but then grows to care for Shego as they realize they are all in this together. And the story could revolve around their journey to discover the origin of the baby and keep it safe.
Shego might love fanfiction because it offers a chance to explore different versions of herself. In fanfictions, she could be portrayed in new and interesting ways, not just as a villain. Ron, on the other hand, would probably enjoy the creativity. He could find stories that expand on his own adventures and give him more heroic moments.
There's also 'Shego's Newfound Heart'. Here, Ron accidentally discovers a side of Shego that she keeps hidden from the world. It's a vulnerable side, and Ron's kindness towards her in that moment plants the seed of love. The story is interesting as it shows how Shego, who is usually so tough, begins to soften around Ron and how their relationship evolves in a rather unexpected way, considering their different backgrounds and initial enmity.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Ron and Shego kiss' and you'll likely find some interesting stories.
