Mal could be a great addition. His relationship with Alina adds an interesting dynamic. He could be jealous of the Darkling's closeness to Alina and cause some tension. Also, Genya. Her skills as a Tailor and her own experiences in the Ravkan court can bring in more political intrigue and a different perspective on the relationship between Alina and the Darkling.
I would recommend 'Shadows of the Heart'. In this fanfiction, the story takes a different turn from the original. It explores what could have happened if Alina had made different choices regarding the Darkling. It's full of interesting plot twists and great character development.
Well, 'Shadowed Hearts' is a really good 'darkling x alina fanfiction'. It's set in an alternate universe where they meet under different circumstances. The story is full of tension and their relationship is explored in a very nuanced way. 'Eternal Darkness' is also worth checking out. It plays with the idea of the Darkling's immortality and how it affects his relationship with Alina. And don't forget about 'The Lost Love' which is a heart - wrenching take on their relationship.
One common theme is the power struggle. Alina has her own power, and the Darkling has his, and their relationship is often shaped by who has more power at different times. Another theme is redemption. Some fanfics explore whether the Darkling can be redeemed in Alina's eyes or in a more general sense.

One great 'alina darkling fanfic' is 'The Darkling's Redemption'. It delves into the complex relationship between Alina and the Darkling in a really interesting way. The author does a wonderful job of exploring their characters deeper than what we see in the original work.
The Apparat could be a main antagonist. He might see the baby as a tool to gain more power and control in Ravka. He could try to manipulate Alina into giving up the baby so he can use it for his own political and religious schemes.
Well, it could make them more connected. The pregnancy is a big thing that ties them together in a very physical and emotional way. They might start to see each other in a new light.
Another plot could involve the Darkling's reaction. He might be conflicted between his dark desires and the newfound sense of responsibility towards Alina and the unborn child. He could try to use the pregnancy to his advantage in some power - play, or he might actually start to develop real emotions for Alina because of it.
