Episode Title:
The Cutie Re-Mark Part 1.
Episode Description:
Starlight Glimmer returns to take revenge against Twilight for ruining her utopian society. To do this, she alters Star Swirl the Bearded's time travel spell so it allows her to travel back in time to the point Rainbow Dash performed her first Sonic Rainboom which allowed her friends to obtain their cutie marks at the same time. Twilight and Spike follow after her, but fail to stop her from sabotaging the race. The two return to an alternate present to find that Equestria is at war with King Sombra, yet the map remains and grants Twilight and Spike access to reuse Star Swirl's spell to take them back to the past to stop Starlight. Their second attempt lands them in another alternate reality ruled by Queen Chrysalis.
