The plot could be centered around a time when Harry is feeling extremely homesick. He misses his parents terribly and is having a hard time at Hogwarts. Mrs. Weasley, sensing his sadness, gives him a huge hug that makes him feel like he's finally home. It's a simple yet powerful moment that shows the strength of their relationship.
One possible fanfiction could be set during a particularly dangerous time at Hogwarts. Harry is feeling extremely vulnerable and Mrs. Weasley, being the motherly figure she is, hugs him tightly when he arrives at the Burrow. This hug is so full of love and warmth that Harry feels like all his fears are melting away. It could be a moment of great emotional connection, showing how Mrs. Weasley has become like a second mother to Harry.
Perhaps Harry is feeling a sense of guilt or shame. Maybe he's made a mistake that he doesn't want Mrs. Weasley to find out about, like using a dark spell in a moment of desperation during a battle. So, to avoid her motherly scrutiny, he starts to ignore her. He might be afraid that if she gets too close, she'll figure out what he's done and be disappointed in him.
One possible reason could be that Harry is preoccupied with his own dark thoughts or problems. Maybe he's worried about Voldemort and his plans, and in his distracted state, he unconsciously ignores Mrs. Weasley's attempts to reach out. Another reason might be that he's trying to be independent. After years of being in the wizarding world on his own terms, he might not want to be mothered too much by Mrs. Weasley.
There's also a chance that she'll be hurt. Mrs. Weasley has a big heart and Harry ignoring her could really wound her. She might then become more withdrawn herself, focusing on taking care of her own family and leaving Harry to his own devices, while still secretly hoping he'll come around.
Mrs. Weasley could get a bit angry too. She has a temper, and if she feels that Harry is being disrespectful by ignoring her, she might scold him a bit. However, her anger would come from a place of love and concern. She just wants Harry to be okay and part of the family, and his ignoring her goes against that.
Well, perhaps Harry is feeling lonely and decides to talk to Mrs Black's portrait. He tries to reason with her about the changing times and how pure - blood mania is wrong. Mrs Black, being stubborn at first, slowly starts to listen to Harry. She might then share some tales from her youth that give Harry new insights into the wizarding world's past social structure.
Mrs Weasley uses her words to comfort Harry. She might say things like 'You're a good boy, Harry' or 'You've been through so much, but you're so strong'. Her kind words are like a balm to Harry's troubled heart. She may also share her own experiences of facing difficulties to make Harry feel that he's not the only one and that he can get through tough times too. This long - term emotional support is a key way she shows her care for him.
The plot could develop with Mrs Weasley setting some rules for them. For example, she might say they can't be alone together without supervision.
In this fanfiction, Harry could be born a Weasley and inherit some of the family's more interesting traits. For example, he might have the Weasley's red hair and freckles. His magical upbringing within the Weasley family would likely shape his view of magic differently. He may not be as isolated as he was in the original story, and this could change his personality. Instead of being the 'Boy Who Lived' in a more solitary sense, he could be seen as part of a large, loving family unit, which would influence how he approaches his destiny at Hogwarts and his battles against Voldemort. He might be more confident and less self - doubting, having grown up with the constant support of the Weasley clan.
Maybe Hermione made a decision regarding Ron that Mrs Weasley didn't approve of. For example, if she rejected Ron's marriage proposal in a rather harsh way, Mrs Weasley, who was very fond of Hermione as a potential daughter - in - law, could be extremely disappointed and angry.
