These are all wonderful-but the first is my favorite.
I can see how you could not get the first one down to 100 words-there isn't a superfluous word in the drabble.
The Toby one was very sad, and very much in character-Toby could always condemn himself far more effectively that anyone else.
Also enjoyed the Annbeth/Bram drabble a lot, although when the FF pairing first began, I always thought that it was a problematic pairing because she'd have to sit on a box to kiss him!
And the Josh/Donna drabble hit the mark on what the future held for them.
Nice work-thanks for sharing!
