It depends on the specific fanfiction. Some authors might portray Bernadet cheating on Howard Lemon to add drama and complexity to the story, while others may not take that route.
In many fanfictions, Bernadet doesn't cheat on Howard Lemon. It all comes down to the imagination and creativity of the writer.
There could be a fanfiction like that out there. However, the world of fanfiction is vast. Sometimes, these kinds of stories are created based on the relationship dynamics between characters in the original work. If Bernadet and Howard have a relationship in a particular show or story, a writer might explore the idea of one cheating on the other for various reasons like adding drama or exploring different character traits. But again, without specifically searching on the right platforms, it's hard to say for sure if it exists.
It could be a very dramatic story. There would likely be a lot of emotional turmoil for Howard.
I'm sorry, but I'm not aware of any specific 'Penny and Bernadet lemon fanfic'. It's also important to note that 'lemon' in fanfic often implies adult - themed content which may not be appropriate or allowed in many contexts.
He might have found it by simply using a search engine. He typed in the name of the fandom and 'fanfiction' and scrolled through the results until he found something that caught his eye.
Perhaps Howard gets the door by simply pushing or pulling it with force. Another possibility is that he discovers a code or password to unlock it.
There could also be a scenario where the Avengers travel back in time to seek Howard Stark's help. Maybe they need his unique insights on some ancient technology or a threat that has roots in his era. So they go back in time and encounter him.
There's no official indication in the main Marvel canon that Howard Stark reads Iron Man fanfiction. Howard was a brilliant inventor and businessman, mainly focused on his scientific and entrepreneurial pursuits. Fanfiction is a modern and often fan - created concept that might not have been part of his world view. However, in some alternate universes or fan - speculations, it could be possible, but still not a common or established idea.
Some fanfics depict Howard Stark as having unexpected encounters with the Avengers, perhaps during time travel or alternate universes, leading to interesting plot developments and character dynamics.
Maybe it's because of some past misunderstandings or conflicts that haven't been resolved.
He's often shocked and intrigued. Fanfiction might depict him as both wary and excited about the unknown possibilities of the future.
