"A Case of Zebra Fevah!" AKA "A Health of Information."

HOPING TO SEE: Zecora being cared for by her friends.  She's always depicted so strong and sure, it will be fun and endearing to see her in a position where other ponies get to show their appreciation by helping her back.

DREADING TO SEE: Zecora staying alone in her cot to avoid infecting others.  Sensible, but not exactly fun. Even worse, it most likely means giving her minimal scenes, since there's not much point seeing her lying alone in bed doing nothing.

HOPING TO SEE: Fluttershy braving the Everfree with her animal companions for company, instead of her friends in her quest for a cure.  Sure, it sounds insane to think we'd rather watch a bunch of nondescript beasts over our beloved mane six, but it's high time those freeloading critters paid her back for all her efforts.  Plus, that cute giraffe might join in.
DREADING TO SEE: Fluttershy braving the Everfree with her animal companions for company, instead of her friends in her quest for a cure.  And they useless and sucky.

HOPING TO SEE: New and fascinating creatures of the Everfree.  Dodgy tricksters.  Gruff protectors.  Nightmare fuel.  The works.
DREADING TO SEE: Fluttershy just fleeing from one scary mute monster to another, with no intrigue or wonder.

Of course, that's assuming Fluttershy goes into the Everfree at all, but if not, what other course would the story take to see her find a cure?  Raiding a library for 20 minutes? God, I hope not.
