In a more complex storyline, Evan could get hurt as a result of some sort of conspiracy against the medical practice. Maybe someone is trying to sabotage the hospital and they target Evan as he is often involved in the administrative side. They set up a situation where he is exposed to a harmful substance or gets physically attacked, which then leads to a long journey of recovery and uncovering the truth behind the attack.
One possible scenario in this fanfiction could be that Evan's sickness is a mystery illness. Maybe the other characters in 'Royal Pains' start to worry and try different ways to figure out what's wrong with him. They could call in all kinds of specialists, but no one can seem to diagnose him right away. This would create a lot of tension and drama in the story.
Obviously, Evan would be one of the main characters since he's the one getting hurt. His brother Hank would also play a crucial role. Hank, being a doctor, would be the one to treat Evan's injuries and provide the necessary medical care. Divya could also be involved. She might be the one who discovers Evan after he gets hurt or helps Hank in coming up with a treatment plan.
One possible storyline could be that Shikadai is on a mission and gets caught in an unexpected ambush by a group of powerful enemies. He might be outnumbered and sustain injuries while trying to fight them off and protect his comrades. Another could be that he's involved in a training accident that goes horribly wrong, like a jutsu backfiring on him and causing him physical harm.
Some fanfictions might also center around the medical aspects related to Tucker in Royal Pains. Given that it's a show about a doctor treating patients, the hurt Tucker might face in the medical field, such as difficult cases or professional setbacks, can be a theme. Writers could explore how he overcomes these challenges while dealing with his own emotional hurt.
One possible storyline could be that Brennan is injured during an excavation. Maybe a cave - in occurs and she gets trapped under some rubble. Her team then has to race against time to save her while she struggles with her injuries. Another could be that she is attacked while working late at the Jeffersonian. This would not only lead to her physical hurt but also psychological trauma as she tries to figure out who did it and why.
Maybe Spike tries to prove himself by joining in on a dangerous adventure with the Mane 6. They are exploring an old, abandoned castle filled with traps. Spike, being smaller and not as experienced as the others, steps on a pressure - sensitive tile that releases a volley of arrows. He gets hurt as some of the arrows graze his body, and then the group has to figure out how to treat his wounds while still making their way through the dangerous castle.
The plot could involve Evan getting sick suddenly. His symptoms might be strange, like a high fever combined with an unusual rash. This would immediately cause concern among his friends and family. They would try to take care of him at home first, but as his condition worsens, they realize they need more professional help.
In some fanfictions, JJ could get hurt during a hostage situation. For example, she might try to negotiate with the hostage - taker, but things go wrong and she gets shot. Her injury then becomes a catalyst for the team to work even harder to resolve the situation. Another idea is that she is targeted by a cult because of her work with the BAU. They manage to capture her and inflict harm on her, and the story could revolve around the team's efforts to rescue her and take down the cult. Also, she could be injured in a car accident while chasing a suspect, and the team has to deal with their fear of losing her while also trying to solve the case that led to the accident.
Maybe Nightwing is trying to protect a civilian in front of his brothers. He jumps in front of a dangerous weapon aimed at the civilian. The weapon is some sort of experimental tech that causes a lot of internal damage. His brothers witness this selfless act and it stirs up a mix of emotions - pride in his heroism but also anger towards the attacker. They then have to deal with not only getting Nightwing medical attention but also hunting down the perpetrator.
One possible storyline could be that they are on a case and get caught in a trap set by the unsub. For example, they might be lured into an abandoned building where the unsub has rigged it to collapse. JJ could get trapped under some rubble while trying to protect Penelope. Another could be that they are poisoned during an investigation. Maybe they accept food or drinks from someone connected to the case who has ulterior motives. Penelope might be the first to show symptoms, and JJ is desperately trying to find a cure while also dealing with her own growing illness from the poison.
