Updated Chapter 1 of "Traitor"

Added an extensive scene between Celestia and Discord in Chapter 1.

I considered expanding the scene with the Bearers, but that doesn't really go down any differently than it does in the episode -- Discord's thoughts there are, I think, adequately conveyed by the synopsis paragraph. And I considered expanding the torment of the Wonderbolts, but didn't for two reasons. One, I have actually never watched an episode with them. Rainbow Dash is my least favorite pony out of the Mane 6 -- I certainly don't hate her, but I haven't gone out of my way to watch the episodes that are primarily about her, which means I haven't seen any eps with the Wonderbolts yet, and I prefer not to write characters I've never personally watched. Secondly, I kind of admit I'm pulling a punch here. I'm walking a fine line between Discord being an utter jerkwad and a sympathetic character. While the fact that his torment of Derpy made him feel bad and quit because she was genuinely scared and not pulling the kind of storybook-heroic "Do what you want to me, foul villain, but I will defy you to the last!" kind of crap that more traditional or more military heroes are likely to pull, and her fear reminded him of Fluttershy, was important to his character development... actually watching him torment a screaming Derpy might stress reader sympathies, already on edge because he's being a jerkwad, so that they lose all sympathy for him in the story as a whole. I might not be pulling this punch if I felt I could write the Wonderbolts credibly, but since I feel like I can't anyway... I'm kind of cheating here.

So I'm done with my expansion. I'm hoping to finish the story, or at least have the next chapter out if it turns out the last chapter runs longer than I expect, tomorrow.
