See, it's still weird to me that Hunter doesn't appear much sooner than he did in the show because Luz is literally the "Evelyn" to Hunter's "Caleb". Not matter how many bottles of copium Lumity fans chug this will never change - it's a fact. Luz is the only one in the cast who fits the "witch from another world" theme and she is the only one who's there for his most important moments.

So it's like... why wasn't he introduced in season 1?
