Well, it was a nice episode, and here's the summary according to my view. The beginning starts off with a shock. 5 of Twilight Sparkle's friends don't have their own cutie marks, their cutie marks were SWAPPED! Then, it was revealed that the spell was from a book of Starswirl the Bearded. He could not get the spell right. Then, Twilight Sparkle thought to make her 5 other friends remember their original destinies. After returning them to their original destinies, she writes her own spell, that required the use of the Elements of Harmony. Then, after the spell is recited, the Elements of Harmony 'eliminate' Twilight Sparkle.

Think she disappeared for eternity?

NOT!

Twilight Sparkle then finds herself in the blank void of space, and Princess Celestia approaches her. She then says Twilight has done well throughout her life and studies and is worthy to be an Alicorn. Twilight was then turned to an alicorn. Her friends were then amazed at her amazing transformation.afterwards she was coronated as a princess. Then, everypony rejoiced that Twilight Sparkle was already a princess. Then, Twilight's brother, Shining Armor, was touched that she became a princess. Then, Twilight Sparkle was seen riding a carriage to Celestia knows where.

Sorry if there was any awkward phrasing.

I will give this episode 8 out of 10. It is nice and touching for Twilight Sparkle to try to get her friends to return to their original destinies.
