Some plot ideas could involve a prophecy about the two of them. For example, a prophecy that says they will either save the entire universe together or be the cause of its destruction. This would create a lot of tension and moral dilemmas for them. They could also find themselves in a situation where they are separated by different time periods, and they have to find a way to communicate and reunite. Maybe there's a device that allows them to send messages across time, but it's being hunted by an enemy who wants to keep them apart.
Well, a great plot idea might be that the 12th Doctor and Clara accidentally end up in an alternate universe where their roles are reversed. Clara has to be the one to save the Doctor this time. Also, they could encounter a race that feeds on emotions, and their strong bond becomes a target. A more light - hearted idea could be that they enter a time - based competition where they have to complete various tasks throughout history to win a prize.
A more emotional plot could be that Clara discovers she's pregnant and is initially scared about how the Doctor will react. She's worried he'll leave because he's always been so independent and on the move. But the Doctor surprises her by being overjoyed and they start preparing for a life together with the baby, facing all the challenges that come with it.
One idea could be that they have to deal with the challenges of pregnancy while also facing a new alien threat. The Doctor's knowledge of the universe might help in finding ways to protect Clara and the unborn child during their adventures.
One interesting plotline could be Clara accidentally getting trapped in a time loop and the 10th Doctor having to figure out how to break it. He uses his wits and knowledge of time mechanics to save her.
One interesting aspect is the depth of their friendship. In fanfiction, they often go on adventures that strengthen their bond. For example, they might face a particularly difficult alien threat together, and through that, their understanding of each other grows.
The contrast between the 5th Doctor's personality and Clara's makes for great storytelling. The 5th Doctor is more laid - back and perhaps a bit more old - fashioned in his ways, while Clara is a very modern, assertive character. Their interactions can lead to some really unique and engaging plotlines.
One great '12th Doctor Clara fanfiction' is 'The Lost Adventures'. It beautifully captures the complex relationship between the 12th Doctor and Clara. The story takes them on a journey through time and space where they face an ancient alien threat that challenges their bond. Another one is 'Clara's Choice' which delves deep into Clara's character and how she makes difficult decisions while traveling with the Doctor. It shows her growth and her impact on the Doctor's life.
One great story could be 'The Lost Adventures of the 13th and Clara'. It often delves into their time - traveling escapades and the unique bond they share. The Doctor's 13th incarnation's quirkiness combined with Clara's tenacity makes for an exciting read.
Another plotline could be the aftermath of the kiss. Maybe the Doctor is conflicted because he knows his nature as a Time Lord and the complications it could bring to their relationship. Clara, on the other hand, is determined to make it work. This creates a lot of emotional turmoil and interesting character development as they navigate their new relationship status.
One of my favorite moments is when they face a seemingly impossible foe in fanfiction. Clara's quick thinking and the Doctor's knowledge combine to outwit the enemy. It shows their great teamwork.
One idea could be that the reader is a time - traveler from the future who has come back in time to prevent a great disaster that the 11th doctor is unknowingly about to cause. This would create a lot of tension and mystery as they both try to figure out what's really going on.
