Just confirming for Season 19:
- Yes, the Season 7 rewards (snowy portrait + Red Unihorn) will be returning, earned upon completing Chapter IV.
- Yes, there are also additional Season rewards coming for completing the whole Season Journey, similar to Season 17’s Galactic Wings; it will be both a unique portrait frame and a unique pet.
That does mean you get two pets for completing all of S19. I’m pretty excited, not gonna lie.
