Twilight Sparkle has important friendship problems to solve. However, that's hard to do with a "reformed" villain following you around all day.

(Context for later readers: This is based on the old Season 5 buzz when Starlight Glimmer — who got beaten in the Season 5 opener but escaped — canonically showed up in the background of the café in "Amending Fences". It was a big deal at the time.)

Sunset Shimmer has learned a lot about friendship. Probably almost as much as her mentor Twilight Sparkle.
But it takes a trip through the mirror to reveal just how far she has gotten in her studies, and how far she has really followed her mentor on the road of friendship.
