My theory: Lloyd's speech reached the First Realm thanks to the dragons.

So, dragons can travel between realms. Perhaps, at the time Lloyd(season 9) gave his Resistance speech, a dragon was traveling from the First Realm to Ninjago, or from Ninjago to the First Realm, and the message carrying the speech was transmitted along that route. submitted by /u/Unlikely_Art2360 [link] [comments]
