Well, a plot could be centered around Loki and Darcy trying to figure out how to raise the baby in two very different worlds. Loki is from Asgard with its own set of rules and traditions, and Darcy is from Earth. They could struggle with deciding which cultural elements to pass on to the child. Also, since Loki has had his share of enemies, they might be worried about someone coming after the baby as a form of revenge. Or perhaps the pregnancy is affecting Darcy in strange ways due to Loki's otherworldly nature, like she starts to have visions of Asgardian places or events related to the baby's future.
Well, a cool plot could be Darcy discovers a hidden power within herself while being around Loki. Loki, intrigued by this, decides to help her master it. Along the way, they face challenges from both Asgard and Earth. Maybe some Asgardians think Darcy is a bad influence on Loki and try to separate them. Meanwhile, on Earth, SHIELD is also suspicious of their alliance. It could lead to a lot of action and some unexpected friendships and romances.
A plot twist could be that Loki's dark circles are actually a sign of a hidden power. In the fanfiction, as Loki discovers this, he has to learn to control this new aspect of himself. It could be that the darker the circles, the more powerful he becomes, but he also risks losing his sanity if he doesn't master it.
The popularity also lies in the fact that both characters have a large fan base individually.

It allows for a wide range of storylines, from romantic adventures to stories of self - discovery. There's just so much potential in exploring how these two would interact and fall in love.
One possible outcome in this fanfiction could be that Loki kidnaps Darcy for a very specific reason.

Well, a frequently seen theme is the discovery of self - worth. For Loki, through his interactions with Darcy, he starts to see his own value in a new light.

One plot idea could be that after the kiss, they face opposition from their families. Darcy's family might think Elizabeth is not of a high enough social standing, while Elizabeth's family could have misunderstandings about Darcy's intentions. Another idea is that the kiss is a spur - of - the - moment thing during an argument, and then they have to deal with the emotional fallout and realization of their feelings. Maybe they are in a public place when they kiss, and it causes a scandal in their society, forcing them to either confront or hide their relationship.
Another plot twist could be that the reader has some sort of power or knowledge that Loki needs. So, instead of a malicious kidnapping, it's more of a strategic move on Loki's part. He might be trying to bargain with the reader to get what he wants, but as time passes, he starts to develop feelings for the reader.
One possible plot twist could be that Loki actually has a noble reason for kidnapping Tony. Maybe he wants to use Tony's intelligence to stop a greater threat that the other Avengers are unaware of.
