My Little Pony: Friendship is Magic - Season 4 Bingo Chart 1.2

In case you didn't notice the description, this is a revised version based on some of the feedback I received. Happy hiatus everypony!

To advance:
>Argument between friends
Q: You mean the basis for nearly every episode?
A: Sort of. I'm leaning more to a serious disagreement. What's the worst conflict that has happened internally so far? I wouldn't include light banter, but would only check this if it were the major focus of an episode.
>Twilight struggles with princess duties
Q: This’ll be the first episode, calling it
A: Yep. That's a gimme too, I think. The horrible outcome would be if I DIDN'T get to check this one, and she just automatically succeeded at everything princess-related.
>Pinkie shown with straight hair
Q: Why?
A: My initial thought was to just hope to see Pinkamena, but honestly I'd enjoy any callback to Pinkie with straight hair. Why? Why not?
>Celestia backstory
Q: Didn’t we already have this?
A: To a degree, yes. We know some things about her, but there is still plenty we do not know. A lot of comments I've read on EQD have talked about wanting to know how her mane turned from pink to its current state / how she became a princess / something more substantive than what we already know. This one fails in specificity simply because I can't predict what elements of that backstory I think will exist, but I feel like a lot of folks would like to know more about her.
