See, I don't think that the Pevensie kids were uncanny and dangerous upon returning to England so much as just like. Cool weirdos.
Lucy talks to animals sometimes. She doesn't expect responses or anything; it has the same energy as a person talking to their dog, except it's the squirrel she spotted on the quad or the racoon in the garbage. But she's super friendly in general so after the initial "what the heck" everyone shrugs it off because like, yeah, of course she does. She also went with me to a scary doctor's appointment having known me for like five minutes and gave me an incredible pep talk. She's cool like that.
Peter joins the fencing club and day one it's like he's never held a foil in his life and day two he loses to a kid half his size but then after like a month he just absolutely annihilates the instructor. But he's super humble about it and afterwards he helps everyone else out without being condescending at all. And while it's a little weird that he's just Suddenly an expert, people are like, "he's a fast learner, that's cool." He's really industrious in class too, just Peter being Peter. He probably practiced a whole bunch after hours.
Edmund gets extremely weird food cravings sometimes, like "wow, I could really go for chicken liver with raisins right about now" or "you guys know what's great? Gooseberry trifles." And his friends say, "I've never heard of that before but it sounds weird." So Edmund learns to cook and starts making all these vaguely antiquated fancy dishes with weird berries and organ meats and things and shares them around during study breaks and everyone's like "Yo! Pevensie brought food. Cool, thanks Pevensie." And he shares it with everyone, even the kids nobody likes, and it kinda brings people together.
Susan, who was always the Mom Friend, seems to have gotten a power-up because now she Everyone's mom and weirdly people actually listen to her? But she only uses those powers for good. Girl in her dorm not eating enough? Susan's here with snacks and look at that now she's eating. Those guys arguing look like they're about to throw down? Susan says "knock it off" and glares and they do. And her friends are like, "how do you do it???" and she says "You just have to act like you expect to be obeyed." It's very cool, though it can be a bit Much sometimes.
And they're all into mythology now? Like ancient Rome and King Arthur and stuff? That's kinda weird, but not off-putting; lots of kids have mythology phases. And Peter named the tree outside his dorm, but everyone kinda laughs and says "yeah okay." Edmund is adamantly anti-bullying now, it's nice. Susan and Lucy wear a lot of lion-themed jewelry and people definitely Notice, but that just means that they start getting more of it for Christmas/birthdays.
And of course whenever two or more of them are together it's like they've got a conspiracy going on. They're always fervently whispering back and forth, giggling an the million inside jokes they've got, giving each other Looks. And onlookers are mostly just like, "Man, it's cool that those Pevensie kids are all so tight; I wish I was that close with my siblings."
