In some fanfictions, Dean might make fun of Castiel's naivete in a cruel way. Castiel, who is still learning about human emotions and behaviors, is sensitive to such remarks. It makes him feel inferior and unloved. However, these moments of hurt also often lead to a stronger bond in the end, as they force both characters to face their insecurities and the true nature of their relationship.
There are also times when Dean's brash actions can wound Castiel. Say, Dean goes off on a dangerous mission without including Castiel, when Castiel has always been there for him. This makes Castiel feel like he's not an important part of Dean's life. In fanfictions, these situations are used to show the vulnerability of their relationship and how much they both need to work on communication and trust.
One common scenario in such fanfictions is when Dean's actions towards Castiel are influenced by his own internal struggles. Maybe he's dealing with self - loathing or fear of getting too close, and he takes it out on Castiel. This can really hurt Castiel who has been so loyal to Dean. As a result, Castiel may start to distance himself, which in turn makes Dean realize the magnitude of his mistake and start to make amends.
One possible fanfiction could be that Dean gets seriously injured during a hunt. Castiel, feeling a deep sense of protectiveness, uses his angelic powers to heal Dean as much as he can. He then stays by Dean's side, warding off any potential threats, whether they be other supernatural creatures or even humans with bad intentions. Castiel refuses to leave Dean's side until he's fully recovered, and in the process, their relationship deepens, with Dean realizing just how much Castiel cares for him.
One example could be a fanfiction where Dean is physically hurt during a hunt gone wrong. Maybe he's attacked by a powerful demon and sustains serious injuries. This can add drama and tension to the story as other characters, like Sam, have to find a way to save him.
In dean - castiel relationship in such fanfiction, there's often a deep emotional connection. They might show a side of extreme vulnerability towards each other. Their relationship can be intense, with a lot of passion and a sense of 'destined to be together' kind of feeling.
Well, in some fanfictions, Kaname might hurt Zero's feelings by being overly possessive of Yuki. Since both Zero and Kaname have feelings for Yuki, Kaname's actions to keep Yuki close to him could make Zero feel left out and unloved, which would surely hurt his feelings.
Well, in some fanfictions, Artemis might hurt Percy's feelings by rejecting his help. Percy, being the heroic type, offers his assistance in a dangerous situation involving the hunt or something related to Artemis' domain. But Artemis, in her pride and self - reliance, turns him down harshly, making Percy feel unappreciated and useless.
Castiel first wakes Dean gently from the nightmare. Then he sits with Dean and tells him stories about the great heroes in Heaven. He tells Dean that he is also a hero, and that no nightmare can ever truly harm him because Castiel will always be there to protect him. He strokes Dean's hair softly as he talks, which calms Dean down.
Well, in some fanfictions, Inuyasha might hurt Kagome's feelings by being overly possessive. For example, he could get jealous when Kagome talks to other male characters and then say something harsh. Another way could be that he doesn't trust Kagome's judgment at times, like when she tries to come up with a plan to deal with a demon and he dismisses it rudely, making her feel unappreciated.
In the fanfiction world, Castiel being an archangel would bring a whole new dynamic to his relationship with Dean. Dean has always been a bit of a protector of Castiel in a way, but with Castiel as an archangel, the power balance shifts. Castiel might become more distant as he has to deal with archangel business, which could make Dean feel left out. On the other hand, they could also have a deeper understanding of each other. Dean could learn to respect Castiel's new role and Castiel could show Dean that even as an archangel, he still values their friendship and partnership.
A common theme is the exploration of Castiel's humanity. When he's being protective of the hurt Dean, he starts to understand human emotions like love, fear, and worry on a deeper level. This can lead to his own character development as he becomes more in tune with his human side while still maintaining his angelic essence.
