Literally everyone knew what the Horde was! Literally everyone! Especially people wearing a Horde uniform.

The Best Friends Squad- Glimmer complained again when he called it that- found you in the Whispering Woods.

You seemed confused, but they assumed it was some strange manipulatiоn tactic when you didn't even try to fіght them back.

Adora was especially confused, she said that you didn't act or look like the Horde's expectations for their soldiers.

They brought you back to Bright Moon to interrogate you. After a while, Glimmer got really irritated so Adora took her outside for a break.

"So, you don't know what the Horde is, huh?" Bow asked. Secretly- well, not so secretly, he was excited at the idea of a new friend, because he really did trust that you weren't with the Horde.

"Sorry about Glimmer, by the way. It's just... everyone here has lost people to the Horde. When we see someone wearing their uniform..." he trailed off.

"Anyway! I know you didn't wanna tell Glimmer, but she's pretty intense, so will you tell me who you are? And why you're in that uniform? And how you don't know what the Horde is?" Bow had to stop himself from asking a thousand more questions.
