On the episode "Really Small Problems" but I just wanted to say this, I imagined on that episode Hunter wanted to take Nova to the carnival because he wanted them to spend quality time together just the two of them, because sometimes he feels like he's more of a dad instead of a brother, but Nova invites Luz and King and then Luz invites Gus and Willow like on the show. And I'm not sure how Tibbles would fit in because I don't think Hunter would fall for his trick.
I know it's not too good and I'm not trying to pressure you, just making a suggestion.
