Well, the team's reaction would be mixed. Coulson would likely be the father figure he always is. He'd offer support and guidance to Skye and Ward. Fitz might have some scientific curiosity about any potential Inhuman or enhanced abilities the baby could inherit. Simmons would be the practical one, making sure Skye has proper prenatal care. May, on the other hand, would be more concerned about how this new situation would affect the team's dynamics. She might worry that the baby could be a target for their enemies, which would put the whole team at risk.
One possible plot idea could be that Skye and Ward had a brief encounter before all the chaos in the series. Maybe they had a moment of connection that led to Skye getting pregnant. Skye then tries to hide it from the team as she's not sure how they'll react, especially considering Ward's actions later. As the baby grows, there could be threats from Hydra who want to use the baby for some evil plan, thinking it might have special abilities due to Skye's powers and Ward's training.
Skye would probably be cautious at first. She doesn't trust easily, especially when it comes to people who might be on the wrong side of the law. But she's also curious, so she would be interested in what the hackers have to offer in terms of knowledge and information.
They would face relationship challenges. With a baby on the way, they need to redefine their roles in the relationship. Also, there could be trust issues. For example, Ward's past actions might make Skye worry about his ability to be a good father.
One popular fanfiction might be 'Skye and Ward's Unlikely Reunion Kiss'. In this story, after many hardships and misunderstandings, they find themselves in a dangerous situation where a kiss is not just a display of affection but also a sign of trust and a new beginning. It often has a lot of action and emotional elements intertwined.
Skye would be devastated. She had a very complex relationship with Ward. There was a time when she trusted him and even had feelings for him. His death would likely make her more withdrawn and distrustful at first. Coulson would be conflicted. He knew Ward was a troubled soul and had tried to rehabilitate him in a way. His death would be a failure in that regard for Coulson.
A possible development could be that the pregnancy is a result of some sort of experiment gone wrong or right, depending on how you look at it. Their child could potentially have special abilities. Skye and Ward would then have to figure out how to raise a child with powers in a world full of danger and secrecy. They might seek help from other characters in the Agents of Shield series who have experience with such things, like Coulson or Fitz - Simmons.
One common theme is the relationship between Ward and Skye. It could be exploring their romantic relationship, either in a canon - compliant way or in an alternate universe where things turned out differently for them.
People write it because they were intrigued by the chemistry between Skye and Ward in the show. Their relationship had a lot of potential that wasn't fully explored, so fanfiction gives writers a chance to expand on it.
One possible fanfiction idea about Skye could be a 'what - if' scenario. What if Skye had joined a different organization instead of S.H.I.E.L.D.? How would her character develop differently? This could lead to a whole new set of adventures and relationships, perhaps even changing her moral compass depending on the nature of the new organization.
Another option is to check out Tumblr. There are often posts about fanfics, and some users might recommend or even write their own stories about Ward and Skye from Agents of Shield. You can follow relevant tags such as '#Agents of Shield Fanfic' or '#Ward and Skye' to discover new works.
