Woo! So Carewyn’s buddies had a bit of a tiff. Let’s break down this fight in the library, shall we?
Carewyn at this point agrees with you, Tulip, but...
...yeah, she adores Bill to pieces and she’d never say something like that to him. Jacob’s Carewyn’s big brother, but in his absence, Bill has sort of filled the hole he left behind in Carewyn’s life and heart. And no matter how much Carewyn doesn’t trust Rakepick and thinks she only wants to use her, Merula, and Bill for her own purposes, she doesn’t like the thought of putting down Bill’s dreams in the name of “protecting” him from Rakepick’s manipulation.
...Like that.
Oooh! Rowan! Not cool blaming Ben for being under the Imperius Curse! I know you suspected Ben might be R, but...OW.
OW AGAIN, ROWAN! Although yes, in game, Jam City has been making Rowan less front and center, and I’ve justified that by Carewyn and Rowan kind of unconsciously moving apart due to their extreme focuses on the Vaults and academics respectively, this seems like kind of an unfair thing to accuse when it’s not something the player actively chose. Yes, Carewyn didn’t select Rowan to go on various adventures with her (mainly because she thought each friend would have talents better suited to that particular adventure), but even if she had, wouldn’t that fall under “coming around when she wants [her friends’] help?” We don’t have much of an opportunity in game to decide to do fun things with our friends, excluding things that build up our friendship levels like Gobstones, drinking Butterbeer, or eating lunch, and we need those levels at certain places to unlock answers and such, so it doesn’t benefit us to do those things with friends we’ve already maxed out. And for Carewyn and Rowan specifically, the way I see their friendship becoming more distant is largely because Rowan over the last five years has stayed very much the same, while Carewyn has changed dramatically, picking up many friends along the way and becoming the confident, courageous leader that the school needs to protect them from the Cursed Vaults. Carewyn doesn’t resent Rowan for staying the same, as she wishes that she had been as bright, ambitious, loyal, and mature as Rowan was from the start and admires how resolute and unapologetic she is in being herself, no matter what -- but from my writer perspective, I can see Rowan staying stubbornly static while her best friend grows and changes as a flaw. She doesn’t want things to change -- but they are changing anyway.
Okay, so in the game, I had Carewyn respond like this --
But I personally imagine the heart-to-heart going a little differently. While with the group, Carewyn would say that exact thing, but would be unable to look Rowan in the eye, and would change the subject back to the task at hand rather quickly. Then, that night, in the Slytherin common room, Carewyn would wait for Rowan to finish studying in the common room and come up to bed...
