I'm pretty much with Yearg on this one. What bothered me most was the very end, we have all five of our main ponies there. Spike is falling, and the way they save him is Magicless Shining Armor tosses the extremely exhausted Cadence to catch Spike, fly him to the center of town, and use her magic to place the heart?

We have Rainbow Dash and Rarity who, together, could have accomplished all that.

With them handling the Heart and Spike, we had Apple Jack, Fluttershy, and Pinkie Pie all able to worry about the King.

This marks twice we've had the barely developed duo of Shining Armor and Cadence saving the day at the end.

And by now, Twilight should know better then to think she would 'fail' by others helping her. Season three and this still being a complex for her is stretching it.

That asside, the best part of these episodes were varies small jokes throughout, such as RD poking fun at Rarity when they first arrived, or Pinkie Pie showing up in the Fluttershy suit.
