It's hard to say exactly. She might have been a time traveler herself, or perhaps she was a victim of some strange phenomenon in the woods that the Doctor had to solve.
It could be a dramatic and emotional moment. Maybe it was during a dangerous adventure or a tragic event.
It could lead to a wild adventure as his companions race to save him. Maybe there's a villain with a specific motive behind the kidnapping.
It could lead to all sorts of adventures and unexpected plot twists. Maybe there's confusion at first but then they team up to save the universe!
Well, there could be tales of time travel adventures with unexpected twists and turns. Maybe some focus on their complex emotional bond and how it influences their actions. There could also be crossovers with other Doctor Who characters or even other sci-fi universes.
In fanfiction, when the 13th Doctor meets the 11th Doctor, there could be a lot of chaos and fun. They might exchange stories about their adventures. Maybe they would team up to fight a common enemy that spans across their different timelines.
One possible plotline is that they meet in a time - locked situation. They have to work together to break the time lock. Another could be that they meet because of a shared enemy that has somehow found a way to target both of their timelines. They would then have to put aside their differences and use their individual strengths to defeat the enemy.
In fanfiction, when the 11th Doctor meets the 12th Doctor, there could be a clash of personalities at first. The 11th is so full of child - like wonder and the 12th is a bit more reserved. But then they might find common ground in their love for the TARDIS and for saving the universe. They could end up learning from each other. For example, the 11th Doctor might teach the 12th how to be more carefree sometimes, while the 12th Doctor could show the 11th how to be more strategic in dangerous situations.
The story could involve the OC having a special ability or background that complements or contrasts with the 10th Doctor. Maybe it brings a fresh perspective to familiar Doctor Who themes.
Well, it varies in different fanfics. The 11th Doctor could be hurt by powerful villains, or maybe in trying to save someone. It could also be from internal conflicts or emotional stress.
It could be due to various imaginative plot devices created by the fanfiction author. Maybe in a battle with a powerful villain or during a risky adventure.
