Dess has a left-handed mouse
The knight's left-handed....
OTHER evidence...
But just saying "It's Dess" isn't solving alot of the mystery... The real question is WHY is the roaring knight Dess? How? Is Kris and Carol working with the knight? If so, why? To what end?
Even if the roaring knight turns out to be someone else, these questions still stand.

Since the dark world is capable of resurrecting lightners under very specific circumstances, do you think... Dess...?
