How to Make Friends and Keep Enemies

This is how I draw*. Benny is on the left, Caroline on the right.
In case you couldn't tell.

So I mentioned liking the Golden Trio (Harry, Ron and Hermione) in my last post, but didn't really connect it to anything. The point of that was that I kind of see my three main characters -- Caroline, Zeke and Stephen -- forming this sort of bond. What intrigues me about my tio is that Caroline fulfills Hermione's role, not Harry's, but she is definitely the hero of this story (Stephen would be Harry, Zeke, Ron).

When I say Caroline is Hermione, I mean, more along the lines of their initial dynamic -- Harry and Ron are off being best friends, while Hermione is lonely because she's a know-it-all. Zeke and Stephen hit it off really well, because Zeke is very likable, and Stephen is incredibly noble (and stupid about it sometimes). Zeke and Caroline really don't like one another, but share the bond of a common home (not a Hermione/Ron thing, just mentioning it).

So now, I am trying to find a way for them to all become friends. In Harry Potter, they fight a troll and win, Hermione takes the fall for them, and they find out she's not all that bad. I don't know how to do this with Caroline, Stephen and Zeke. Stephen has seen a softer side to Caroline just now, and he was upset when she nearly died, but Zeke and Caroline are a different matter. I'm worried that their years of fighting with one another and hating one another for no real reason, can't be overcome by just Stephen letting her join in the games.

I know I was all excited last post about not knowing what's going to happen, but here I am, worried because I don't know how this will work, and I really want them to be friends. Indeed some of the plot, I sense, will need them to be friends. The real reason they aren't friends now is that Caroline is jealous of Zeke.

Anyways, so I'm writing that.

I'm also finding it amusing that Benny, a character from a seperate novel, is making fun of Caroline and Caroline back at Benny as I write. They have amusing interactions. I wish there was a way to combine their stories, but not really. AH WELL. We solider on.

*This is not how I draw. But its how I draw when I'm feeling lazy/am at work and realize I have no image to go with the post. ;)
