I feel like they're not really interesting at this point theirs no real room to have "development" like what else can you do with the characters at this point? Despite some small parts in ew, it was clear that the characters have grown but don't show a lot of room to grow as the main cast.
I rather they stay semi important characters that pop up a few times in the story instead of the main people we follow for the 3rd time? 4th time for the twins. It's just got to the point where fresh new faces new stakes, knowing that what you're doing comes with risks, HW was good for the reason you felt like people didn't just have plot armor it kind of ruins the characters if they all have plot Armor and theirs no stakes or fear of loss.
