Another reason might be related to a new piece of technology. For example, if there was a malfunction in some experimental Stark Industries device that emitted some sort of energy wave. Pepper, being close to it, could have been affected and passed out as a result.
Perhaps he freezes for a moment. The shock of seeing Pepper pass out might be so great that he's initially stunned. But then he quickly regains his composure and uses his scientific knowledge and resources to figure out what's wrong and how to help her.
It could be an attack from one of Iron Man's enemies. They might target Pepper to get to Tony.
Pepper could be kidnapped and tortured by one of Iron Man's enemies. This would drive Iron Man into a frenzy to rescue her. He would use his suit's advanced tracking capabilities to find her location. Once he does, he'd have to fight through hordes of bad guys to get to her. After rescuing her, he might become more protective and even consider retiring from his superhero duties.
It could also be due to extreme exhaustion. Harry often gets involved in intense battles or has to endure long periods of stress. For example, if he's been fighting multiple foes continuously without a break, his body and magic might give out, leading to him passing out.
One of the main emotions is passion. Fanfictions often depict their relationship as very intense. So when they kiss for the first time, it's a moment of pure passion. But there's also a touch of vulnerability. They are both exposing their true feelings, and that can be scary. Tony, who is usually so confident, might be a bit hesitant, and Pepper, who has to deal with Tony's complex life, is taking a risk by showing her love so openly.
In many Iron Man 3 Pepper and Tony fanfictions, their relationship often evolves in interesting ways. One common theme is how they deal with the after - effects of Tony's trauma from the events in the movie. For example, Pepper might be more protective of Tony, and Tony, in turn, might try to be more open with her about his fears. Their love can be shown through small gestures like Pepper making sure Tony eats well during his late - night tinkering sessions, and Tony surprising Pepper with a small but meaningful gift, perhaps a piece of jewelry he designed himself using his high - tech resources.
One great Iron Man Pepper and Tony fanfiction is 'The Heart of Iron'. It beautifully depicts their relationship, showing Pepper's unwavering support for Tony in his superhero and business endeavors. The story delves deep into their emotions and how they grow together through various challenges. Another one is 'Stark Love'. It focuses on the more intimate and private moments between them, like their quiet dinners and shared secrets. It gives a very warm and loving portrayal of their relationship.
One of the favorite scenes in Iron Man 3 Pepper and Tony fanfictions is when Tony shows Pepper his latest Iron Man suit upgrade. He's like a kid showing off his new toy, and Pepper's reaction can range from amused to impressed. It's a sweet moment that shows their closeness and how much Tony values Pepper's opinion.
One idea could be a story where Tony is overly protective of Pepper during her pregnancy. He starts inventing all kinds of baby - related gadgets, like a super - advanced baby monitor that can also analyze the baby's health in real - time. Maybe he even tries to build a mini - Iron Man suit for the baby before it's born.
It could be that Pepper gets injured in a terrorist attack on Stark Industries. Iron Man is away on a mission when it happens. When he returns and sees her in a hospital bed, he is devastated. He starts to re - evaluate his life and the risks he takes that might put Pepper in danger. He decides to upgrade the security at Stark Industries and also to be more cautious in his superhero activities to ensure Pepper's safety in the future.
