Chrysalis has her minions battle the Mane Six, and they manage to successfully capture them and returned them to her.

Trixie and Starlight inform this to Discord, that Chrysalis has captured the princesses, flurry heart, Twilight and her friends, which include you. And you're Discord's friend, or he likes you more than that. When he heard this, he got a bit protective and immediately asked.

"Yes!" Starlight replies.

"Where." He asks.
