Climbing castle/Fantasy

There is a raised platform in the playground that can only be reached by climbing either a rope net, a ladder, a climbing wall or a spider web of ropes. The four places these reach the platform have a pole you need to climb under while the rest is covered by a wall with 'crenellations' like a castle. You remember racing friends to the platform so you could be 'king of the castle' (despite consciously knowing that it never happened, or if it did it wasn't here). You decide to see if Christy has decided to be 'queen'.

"Hey!" she whines as you reach the top of the ladder, standing up. "No fair John. You have a torch."

"If I didn't" you answer "I wouldn't have been able to see anything, let alone find you. It's so dark."

"I guess that's true" she admits. "Serves us right for playing here at night."

"So is it my turn to hide?" you ask.

"No" she says "I don't have a torch..."

"You could use mine" you offer.

"... then you couldn't see and you might hurt yourself." she says "Anyway I want to play something else."

"Such as..?"

"Um ... we are in a castle so maybe I could be a princess and you could be a brave knight who saves me?" she says.

It's a cliche and you wouldn't mind being Christy's 'hero' if she decides to 'reward' you with a kiss (or possibly more) but maybe you have a better idea.
