Well, he might be quite reluctant at first. Snape has always had a rather complex relationship with Harry. He might see it as a huge burden and be full of doubts. After all, he has his own grudges and past issues with James Potter, Harry's father. But on the other hand, he also has a sense of duty towards Harry as he was Lily's son. So it's a mix of emotions that he has to deal with.
He would likely be very hesitant. Snape is not exactly the nurturing type. He's a strict and often brooding character. Adopting Harry means taking on a parental role, which is completely foreign to him. He may initially resist the idea, thinking that Harry would be better off with someone else, or that he himself is not fit to be a father figure. But deep down, there might be a part of him that feels a connection to Harry through Lily and that could start to change his mind over time.
One big challenge is their pre - existing relationship. They've had a lot of conflicts in school. Snape has been rather harsh on Harry, so they need to overcome that animosity. Also, Snape has to deal with Harry's trauma from the Dursleys. He needs to help Harry heal and grow in a positive way, which is not easy for someone as emotionally reserved as Snape.
In this fan fiction, Snape might adopt Harry because he realizes that Harry has a lot of potential that is being stifled at the Dursleys. He could take Harry to a secret location and train him not only in magic but also in self - defense and survival skills. Snape would have to deal with his own complex feelings towards Harry, as he has both resentment and a sense of obligation. And Harry would have to adjust to living with Snape, who is not exactly the warmest person. It could be a story of growth and understanding between the two.
Harry might become more reserved and cautious at first. Growing up with Snape, who is not as openly affectionate as others, would make him more self - reliant. He'd also likely become more skilled in magic quicker, as Snape is a very talented wizard.
At first, Harry might be extremely suspicious. Snape has always been cold and mean to him in the past. He would wonder what Snape's true motives are. Harry is used to being on his own and not relying on Snape for help, so this sudden rescue would be very unexpected.
In the fanfic, Snape might use his knowledge of the Dursleys' house layout. He may enter the house unnoticed, find Harry, and then use a Portkey to quickly get them both out of there. He could also have some sort of charm or potion that he uses to counter any magic the Dursleys might have used to keep Harry there, like a spell - breaking potion. And he may have planned the whole rescue very carefully, choosing a time when the Dursleys are least likely to notice, like in the middle of the night.
Perhaps Snape uses magic to create a distraction at the Dursleys' place. He could make strange noises or apparitions that scare the Dursleys, and while they are in a panic, he grabs Harry and disapparates. This would be a quick and efficient way for him to rescue Harry.
Snape is likely to be initially suspicious. He has long held a rather negative view of Harry, so when he discovers Harry is good at potions, he might think Harry has some ulterior motives or has received improper help. After all, in the regular Hogwarts setting, their relationship is quite tense.
In this fan fiction, Snape's character development is quite remarkable. At first, he might be hesitant and conflicted about saving and adopting Harry. But as time goes on, he becomes more selfless. He has to learn to communicate better with Harry, which is a big change for him. He also has to face his own demons from the past, like his relationship with James Potter. This journey of self - discovery and growth makes his character more three - dimensional and likable in the context of the fan - made story.
In this fan fiction, Snape's character development could be quite complex. Saving Harry is just the starting point. With the blood adoption, he is thrust into a new role. He may initially struggle with this new identity as a sort of surrogate father. However, as time passes, he could learn to love Harry in his own way. His development might also involve him reconciling his past actions, especially those that were harmful to Harry in the past. He could become a more well - rounded character, showing both his old prickly side when dealing with others at Hogwarts, but also a soft, caring side when it comes to Harry.
Well, initially, Harry might be resistant to the idea of being adopted by Snape. He may think it's some sort of trick. But Snape, with his own sense of duty and newfound affection for Harry, tries to break through that resistance. As they spend more time together, Snape might share his own experiences at Hogwarts when he was a student, which helps Harry relate to him. And Harry, in return, might show Snape the good qualities he has inherited from his mother. This exchange of vulnerabilities and shared experiences gradually deepens their relationship into something more like a real father - son relationship.
