The notes from the beginnings of the 1st two chapters cover everything, I think.
Ron headed up the stairs as his dad headed into the kitchen for some milk to settle his stomach. He knew his parents supported him, but he also knew why his dad was prone to having an upset stomach. Still, he was glad his dad wasn't feeling well tonight. If he hadn't been sick he wouldn't have been up, and if he hadn't have been up they wouldn't have been able to talk.
He had to admit, the talk helped. A lot. But a few hours sleep was still the best looking thing he could think of at the moment. "Well," he thought to himself, "maybe not best, but definitely top five."
But as he approached his bedroom door, something felt weird, like there was another presence in the house. He stopped a moment, and then threw the door wide open, hoping to use the surprise to draw the intruder out.
Nothing. Thinking he had probably just overreacted, he went on into the room, finishing the job his dad had started on his shirt.
When he saw Kim asleep on the bed. She had changed into her capris and camo top, and snuck in through the window. "God she is so beautiful. Whatever I did to deserve her, I have to have done it in a past life, because I KNOW I didn't do it in this one. Hey, what's that?" He had noticed a sheet of paper under her hand. He picked it up slowly, trying not to wake her. "A letter."
"Dear Ron,
Cat's out of the bag, huh? It feels like it should be the most natural thing in the world, but it's still kind of scary. I talked to my mom tonight, and that helped a little, but not much. I don't know what could happen if I keep this in, but I know it can't be good, so I'm just going to say it: I'm scared of you getting hurt out there. I'm not saying I don't think you can cut it because I know you can, but I'm still scared. I always have been, but now it's like every nightmare I've ever had about losing you just got shot full of heart-shaped steroids.
But this isn't me backing off. You don't get off that light. You're just going to have to learn to live with a girlfriend who's with you, get this, BECAUSE you keep company with strange rodents, have horrible table manners, and can't shut up even for just five minutes.
Just kidding. I love Rufus, your table manners are fine, and I don't mind that you can't shut up for even five minutes, because you can't go two without making me smile.
When I'm with you I don't have to be Kim Possible: Hero or Kim Possible: Kung Fu Queen. All I have to be is Kim Possible. No adjectives, just me.
I'm in. All the way.
Kim"
Ron stood there, going over the letter again in his mind. He didn't know how he felt about it. On the one hand, he had proof that Kim felt the same way he did. He wanted to jump up and down and scream "KIM POSSIBLE IS MY GIRLFRIEND!" at the top of his voice.
But she was hurting. Because of him. He might not have done anything to her, but she was still hurting because of him.
A voice that seemed to be both his and not his, in his mind and all around, said "Not because of you."
"Yes, because of me. She's worried I'll get hurt, so she's worried because of me. Who's there?"
"She isn't worried about you getting hurt."
"Then what's she scared of? Show yourself!"
"She's scared of not being able to prevent you getting hurt."
"She thinks she isn't good enough?" Ron asks, stunned by the idea.
"Yes."
"Oh Kim." Ron kneels beside his bed, putting him at a face to face level with Kim. "I've never worried about getting hurt. I knew the job was dangerous when I took it. Buck Buck Buck Buck." laughs. "I'll be fine. Don't worry." Addresses the voice. "Thank you, but you never answered my question. Who are you?"
"You know, Stoppable-san."
"No, I don't"
"You do; in time you will embrace it. For now, however, there are other things that need embracing."
Ron turned back to Kim, and saw that her face was scrunched up and her upper lip was starting to quiver. Ron had seen this before. His Kimila may be fierce, but she isn't vicious, and doesn't have a mean bone in her body. But to do what she does asks her to do mean things. It's always cost her, and this is how she's paid. Not after every mission, but the badder the fight, the bigger the price. From the looks of her cheeks this was going to be bad. Before, he'd always jest let it go. Not happily, but he thought of it as "just something Kim has to do."
Now, though, this thing was happening on his bed, on his turf. And he'd be damned if anything happened to Kim on his turf.
Climbing into bed, Ron put his right arm around Kim's waist. With his left hand he began stroking her hair, grimacing with rage every time he grazed her cheek. Then he started singing. Kim always razzed him for knowing this song; he hoped it would help.
Oh, why you look so sad?
Tears are in your eyes
Come on and come to me now
Don't be ashamed to cry/ I can see you through
'Cause I've seen the dark side too
When the night falls on you
You don't know what to do
Nothing you confess
Could make me love you less
I'll stand by you
I'll stand by you
won't let nobody hurt you
I'll stand by you
So, if you're mad, get mad
don't hold it all inside
Come on and talk to me now
Hey, what you got to hide?
I get angry too
Well I'm a lot like you
When you're standing at the crossroads
and don't know which path to choose
Let me come along
'Cause even if you're wrong
I'll stand by you
I'll stand by you
Won't let nobody hurt you
I'll stand by you
Take me in, into your darkest hour
And I'll never desert you
I'll stand by you
And when . . .
When the night falls on you, baby
You're feeling all alone
You won't be on your own
I'll stand by you
I'll stand by you
won't let nobody hurt you
I'll stand by you
Take me in, into you darkest hour
And I'll never desert you
I'll stand by you
I'll stand by you
Won't let nobody hurt you
I'll stand by you
Won't let nobody hurt you
I'll stand by you
It helped. Her back stopped heaving into his chest, her breathing steadied, and she snuggled closer.
"Mmmmm . . . Ron." She said in her sleep.
"Kim." He didn't need to say anything else. His left hand stopped stroking her hair and moved under the pillow to seek hers out. He kissed her gently on the neck, and drifted off to dream with her in his arms.
