Talk:Twilight's Kingdom - Part 2/@comment-24092299-20140508003207/@comment-11159205-20140508095256

Princess Twilight Sparkle had a (3-minute) subplot about Twilight choosing between the responsibility of Equestria and her friends

And now they are actually acting upon it. '' Twilight does just the opposite, and chooses her friends over the magic. It seems kind of odd.''

Friendship is Magic. Read the subtitle of the show, and just think about it.

''How did her friends get captured in the first place? It would seem very likely that they would all stick together in these kinds of crises.''

Probably when Discord betrays them.

If she sacrificed her magic, that basically means that Tirek wins, because she had no idea that would make her key appear

Tirek may not be aware of the box or the keys, so there is no reason to suck anything out of it, and the whole magic power fight was just ending in a stalemate anyways, so nothing was going to be gained out of it out of a prolonged fight.

Simply put, Twilight's powers alone is not enough to stop Tirek.
