S01E06 — Overpowered

One day at school, Sunset Shimmer's empathy powers get so out of control that she starts hearing others' thoughts without touching them, and she discovers her friends are experiencing the same thing. As they wonder why, Rainbow Dash zooms in with her super speed, bragging about using her powers to do everything. Twilight theorizes that, because their magical geodes are connected, the more each of the girls use their powers for everyday tasks, the more they get supercharged. So they agree to use their geodes in moderation. When Zephyr Breeze enters and asks Rainbow out on a date, Rainbow is about to use her super speed to run away, but her friends warn her not to, and she simply walks away from Zephyr. Later, Sunset's powers return to normal.
