While short in a drabble-like way, i really liked this. Have you ever read any stephen king? Cause he does thing were he'll put thoughts, or little tangents in side brackets. I thought you did a really good job with that.

Aw, that really was perfect. Very cute.

This was good! I enjoyed it! :D

Heaven and Earth

Ooh, this is so good! I definitely like the style; it's a nice change. And it's a very IC take on the Derek/Casey dynamic. Nice job!

i really liked it!
the different style is pretty neat i like it
great job!

That was good! Reminiscent of the amazing WhenLighteningStrikes. Loved all your parenthetical comments--tapping into their brains is so much fun, isn't it?

You did very well writing in this style for the first time. I think you should try to write more in this style.

I really liked this, the style, the description of their game, and all the contradictions in his head. I really liked the end with the promise of university where they won't be known as step-siblings. Great job!

Oh, this was really good! (I'm guessing you have the same LJ, right?) I really liked the transition from the beginning lines to the end (that "You look like the ugly stepsister from Snow White" still cracks me up) and I loved the second person Derek-POV. Because his thoughts are the most interesting to explore.
And that commentary on their life was fab! Like he spends so much time pranking her simply because *she'll* have to spend all her time thinking of ways to stop him. So basically, they're always on each others' minds! :)
And your interpretation of that last scene was certainly different. Not the end, but just a to be continued...
Nice work! :)
